Good King Henry and Sea Kale from seed

Perennial vegetables, what's not to love!  You plant them once and harvest forever.  Not all perennial vegetables produce seed, but Good King Henry and Sea Kale are two perennial vegetables that are simple to grow from seed.


Good Kind Henry (Chenopodium bonus-henricus, sometimes also called Blitum bonus-henricus) also called Poor-man's Asparagus, Perennial Goosefoot, Lincolnshire Spinach, and a few other names is a nice perennial vegetable that is rarely grown in Australia.  It dates way back to neolithic times and was common in every garden in Europe prior to the Spanish bringing back all the vegetables we commonly grow from South America.  It is hardy, delicious, perennial, good for you, and best of all it has a fun name.

Sea Kale (Crambe maritima) is another perennial vegetable that is rarely grown in Australia.  It was also commonly grown across Europe prior to the the Spanish returning from South America with all of the vegetables we now commonly eat.  It is hardy, perennial and good for you.  I am not a huge fan of brassicas but people who like cabbage tell me that Sea Kale tastes great.


There are very few named varieties of Good King Henry and Sea Kale.  People grow these perennial vegetables from divisions and root cuttings and often complain that it is impossible to germinate their seeds.  The internet is filled with misinformation and complaints about how difficult they are from seed, so much so that many people warn that it is not even worth trying.  I have never bought any seed after reading these warnings so have never tried to germinate them before now. 

As luck would have it, I have been sent some seed of several named varieties of Good King Henry and Sea Kale.  Each of these named varieties are apparently superior to the un-named ones.  I have been told that they will grow true to type as they have been isolated, but to be honest I don't know if that is true or not.  I will find out soon enough and be able to grow the best plants from division after that.

I should write another blog post later on each of these perennial vegetables and their uses and taste as they are worthy of mention, but for now I want to write about how easy it is to grow Good King Henry and Sea Kale from seed.


Growing Good King Henry from seed

Being a Chenopod they tend to dislike being planted and prefer to self seed.  That is great, but I have to plant the first seeds or they will not be in my garden.  I have also been told that they have low to no germination rates.  I have a decent number of seed but kept it simple to begin with.

I soaked 10 seeds of each variety of Good King Henry in warm water for an hour.  I would have preferred overnight but did not have that luxury this time.  I then planted in a seed flat on a heat mat and kept moist just as I would tomato seed.  It is a bit cold at the moment, but I wanted them out of the way before it was time to plant tomatoes.

One week later the tiny seedlings started to sprout.

That certainly didn't seem overly difficult, I didn't do anything special other than soak briefly and provide heat.

I will try to compare the different varieties once they are larger and I am able to see how they fare in the garden and can taste them.


Growing Sea Kale from seed

I have heard horror stories of sea kale seed.  People complain that they never germinate for them without rigorous stratification etc, I have read that seeds take months or even years to germinate, I have also heard that viable seeds float.  Apparently none of those things are correct.  Again I have a decent number of seeds but kept it small scale to begin with.  All of the different sea kale varieties have seeds that looked different which was unexpected.

Sea kale seeds are each covered in a foam like pod.  I cut that pod off 10 seeds of each variety and soaked them for an hour in warm water.  Again I would have preferred overnight but did not have that luxury.  The seeds all expanded and sank.  I planted them in a seed flat on a heat mat and watered them.

A little over a week later the seedlings started to sprout, much like any other brassica.

That was a bit more work as I had to remove the seed coat, but it certainly was not difficult.  Perhaps people have issues as they do not remove the seed pod?  Common sense suggests that the pod needs to be removed just as it is in any other brassica.  Leaving the seed pod on would certainly make sea kale seeds float and would prevent germination for months or years as no water could get in to the seed.

As above I plan to compare the varieties and see which are best in my climate.


Where to get Good King Henry and Sea Kale in Australia

At this stage there are a few places that sell seed of Good King Henry as well as Sea Kale, to the best of my knowledge none of them have any named varieties.

After I have grown them and compared them I will probably list seeds or divisions from the better varieties of Good King Henry and Sea Kale on my for sale page.

Breeding New Micro Tomatoes

A while ago a very generous person gave me some seeds from a miniature dwarf variety of tomato called Micro Tom.  I am very fond of this variety and am slowly building up numbers of seeds and distributing them to other growers.  This variety carries several miniaturising genes which mean that it only grows a tiny plant less than 10cm tall, this tiny plant can produce a small number of cherry tomatoes.  These cherry tomatoes taste ok and I believe the plants are meant to carry some genes for resistance of various diseases.

Breeding vegetables is enjoyable, but too often progress is slow due to only being able to grow one generation per year.  Creating a new variety of tomato often takes 5 to 10 years or more!  Breeding micro tomatoes can be a lot faster.

In any breeding endeavor the lack of space is always an issue.  After selling the property I no longer have the luxury of space which makes the problem worse.  This has started me thinking a lot more seriously about breeding a few new types of micro tomato by using Micro Tom or another micro tomato as one of the parents.  While I am trying to build up numbers of Micro Tom seeds and distribute them I am also using a small number in breeding projects.
Micro Tom tomato

Micro Tom Tomatoes are good, but they could be better
Micro tomatoes have very short life cycles so several generations can be grown per year.  They are often used in studies as a model organism due to their short life cycle.  From planting the seed to harvesting the fruit and planting that seed takes a little over 3 months.  I can potentially grow 3 to 4 generations a year, this means creating a new variety can take as little as 2 years (but probably a bit more than that).

Micro tomatoes take up a small fraction of the space of a regular tomato which allows for more plants to be grown in a small space.  Growing more plants means faster progress.  Space is always limiting when breeding new vegetables, even if I had acres of greenhouse space I could always use more to create more varieties a lot faster.

People overseas are breeding many new types of micro tomatoes, unfortunately we have no access to them in Australia as importing tomato seed legally is expensive and difficult.  To that end, if we are to have better micro tomatoes then someone in Australia will need to breed them.
Micro Tomatoes

Someone should breed better micro tomatoes
Micro tom, while cute as a button, is not the tastiest tomato in the world.  It is not bad, but it is not great either.  Someone should breed a tastier micro tomato in Australia.

Micro tom, while reasonably productive, could be a lot more productive.  Even though it takes up such little space it would be nice if it were more productive.  Even though it grows and crops well in a small cup of soil I still think the more productive the better.  Someone should breed more productive micro tomatoes in Australia.

Micro Tom grows cute red round tomatoes.  While this is lovely it would be nice to have more variety, apparently there is a small range of various colours and shapes of micro tomato fruit overseas.  Someone should breed several shapes/colours of micro tomatoes in Australia.

Micro Tom can and will grow at any time of year if protected from frost and many people overseas grow them indoors over winter.  Unfortunately if the temperature is too low it can not pollinate properly and can not produce fruit.  While this is only an issue in a small number of places that get cold enough for this to happen it is still an issue.  Someone in Australia should breed micro tomatoes that are more productive in colder temperatures.
One truss with lots of flowers, this would be a good cross for Micro Tom

Some micro tomato breeding ideas
Here are some of my micro tomato breeding ideas.  I have started some of these projects and am several generations through them with plans of releasing some of them soon, others I do not even have the other parent to make the first cross.

Different shaped micro tomato, everyone seems to love roma shaped tomatoes for some reason, so I have started to make a micro roma tomato.  It looks good and tasted great, it is not as productive as it should be but that can be fixed.  When it is more stable and perhaps a bit more productive I may try to sell the seeds through my for sale page.
Micro Roma tomato - the best tasting micro tomato so far
Multiflora tomatoes produce hundreds of flowers per truss, it would be great to have a multiflora micro tomato.  This will increase the productivity vastly making micro tomatoes more than an edible novelty and convince more people to grow them.  This is proving more difficult as the low percentage of leaf area of the micro tomatoes makes creating a tasty multiflora micro tomato a bit of a challenge.  I don't just want a productive micro tomato, I want it to taste good too.  It will happen, it will just take a little longer.
Finding the balance between lots of fruit and tiny plant, this micro tomato is under 9cm tall
Different coloured micro tomatoes are fun and pretty.  While getting the colours in is easy, getting a better tasting coloured micro tomato is the tricky part.  There is little point having an amazing looking micro tomato that does not taste great.  Green when ripe tomatoes tend to taste the best but people tend to shy away from them so I may concentrate on other colours to begin with.  Yellow, tangerine or stripey are always favourites, black (muddy brown) and high anthoycyanin lines are also options.  I dare say I will produce a few different things over the next few years.

Having tomatoes in the midst of winter is great.  Cold weather can prevent pollination in tomatoes.  I would love to one day grow a parthenocarpic micro tomato that can set fruit in cooler weather if protected from frost.  The genes here are a little tricky to work with and I don't have any parthenocarpic tomato varieties to use as parent stock so I have not yet started this project.

Breeding tastier micro tomatoes is interesting as growing conditions play a part in taste.  Different people have different ideas of good tasting tomatoes.  Taste is always going to be one of the traits I want in micro tomatoes.

Breeding new micro tomatoes would be simple and fast if we had access to many types of micro tomatoes with a wide array of genes, but in Australia we don't have access to many at all.  Things go a lot faster if the other parent is a dwarf tomato, but there are so few dwarf tomatoes in Australia that sometimes a regular tomato has to be used.  Luckily it is pretty obvious early on as to which seedlings are micro tomatoes and which are not so culls can be made while the plants are tiny seedlings.


Where to get micro tomatoes
When I have stabilised a few good lines I plan to name them and sell their seeds.  I will most likely list them on my for sale page when they are ready.  This probably won't be for a while yet as I do not have a garden or yard at the moment so progress is slow as everything is growing in pots and most of my seeds are stored away for the moment.

Micro Tomato Seedlings and regular tomato seedlings, it is simple enough to tell which are which

Heirloom Vegetable Seeds Australia

After moving twice in a year, plus the birth of my youngest son, I was not selling many vegetables or seeds for a while but have gotten back into it.  All of the perennial vegetables for sale that I currently have are listed on my For Sale page.  I am adding some new perennial vegetables and herbs there.

I have had a few people ask me where to buy seeds or they have asked my opinion of different companies so I thought I would write a post about some of them.  Some of these companies have bought seeds from me in the past, some I have bought seeds from, others I have heard about from other people.  I have probably forgotten to include some, if I remember them I will try to add them later.

Please note that I am not affiliated with any of these companies and that the views expressed are based on my personal experiences.  I am in no way liable if they do not live up to expectations.  This is based on past experiences and they may or may not treat you better or worse than they have done to me in the past.

Yacon Pineapple slaw


I love yacon, it is sweet and crunchy.  I mostly eat yacon raw, I just peel it, slice it thinly and eat it.  We have tried eating it a few other ways and most were good.  It tends to take on the taste of whatever it is in with so is reasonably versatile.  I have even used some of our yacon roots and water kefir grains to make yacon water kefir which was nice enough even though I prefer regular water kefir.

I normally leave the yacon in the soil until I want to eat it, if I happen to leave it for too long the plant simply gets larger and stronger and returns a larger crop next time.  Recently we have moved from our property into a rented house in town, as such I dug up a small number of yacon plants to grow as well as a heap of the tubers to eat.  Being so hot and dry out here the tubers do not last overly long.  I wanted to find a few new ways to eat yacon as I can not stand the thought of wasting it.  I looked on the internet and stumbled across yacon pineapple slaw.
Yacon growing in a pot - it belongs in the soil
I found a nice sounding recipe, then changed it a fair bit, and made it with a group of school children.  It was delicious and super easy to make.  I am putting the modified recipe here partly to share it and partly so that I have it saved somewhere so I can make it again.

Ingredients:
Yacon tubers, 1 large tuber or a few small ones
1 can of pineapple (or a real pineapple peeled and cut into small pieces)
The juice of 1 lime or a lemon (lemons are the poor cousin of the lime, but they are cheaper)
1 chilli (this can be left out)

Method:
1) Juice the lime (or its poor cousin the lemon)
2) Peel the yacon tuber
3) Grate the peeled yacon
4) Add lime juice to the grated yacon.  Mix together.  You have to do this as soon as possible otherwise the yacon will turn black
5) Cut pineapple into tiny pieces, add pineapple and any juice to the yacon
6) Remove the seeds from the chilli.  Cut up the chilli into tiny pieces
7) Mix it all together and serve

It really doesn't get any easier than this, and it tastes great.  It would be easy enough to add other things to this too as long as they are cut up tiny.  I think something crunchy and relatively tasteless such as shredded cabbage would bulk this out nicely.

Some of the more tropical and fruity tasting chillies could also work well in this as they would add taste but would still be crunchy.  There are a heap of tropical tasting chilli varieties, some have no heat while others are super hot, but few are available unless you import the seeds and grow them yourself.  One great place I have found for chilli seeds is pepper lover, they seem to love what they do and tend to include extra seed packets with orders.  Only some species can be posted to Australia so please do check the AQIS BICON database first.

Overwintering vegetable plants

We have some perennial vegetables which I decided to overwinter.  We moved in Spring so I have not had time to make a post about them until now.  We had the coldest winter since we have lived here and lost a lot of frost tender plants that I normally can overwinter with no effort.  I took a few pictures of some of the survivors.  Most of these plants are far larger now.

Kangkong (Ipomoea aquatica)

This is a heat loving tropical perennial leaf vegetable which is often grown as an annual in cooler climates.  It grows well from seed, but I wanted to see if overwintered plants were larger than seed grown and it appears that they are.  It has many common names and is related to sweet potatoes.  I am not overly fond of leaf vegetables, but I like kang kong.  Unlike many other leaf vegetables it never goes bitter, it can be eaten raw or cooked.  I have only eaten it raw and it tastes nice, apparently cooked it tastes a lot like spinach.

I grew it in too small a pot so it did not reach anywhere near its potential last summer.  I tried to grow it in a fish talk as a floating water plant but there was not enough sunlight and it appears to prefer at least some soil for its roots.  It tried to flower but then winter came and the cold cut it down to a stump.  I do not want to save and plant seed each year if there is an easier way and this plant grows easily from cuttings.  I am glad that this can be overwintered as it is simple and the plants are larger than seed grown.

Once the warmer weather came along it started to grow fast again.  I wish I knew about this plant years ago as it is great.  It dislikes the cold weather and dies back badly even without frosts but survives and grows very fast once the days are warm.
Kangkong resprouting in late winter, it dislikes the cold air even when protected from frosts

Chilli - Trinidad Scorpion Butch T
Most varieties of chilli available to home gardeners can be overwintered easily enough.  Super hot chilli are a lot more finicky than regular chilli and capsicums from what I have heard.  Being the first time I have grown the super hot chilli I decided to try and overwinter it rather than start from seed again.  Strangely it went very well and was very easy.  I tried to keep it out of the frost at night and put it in the sun during the day when I remembered.  I accidentally let it get a bit of frost a few times and forgot to put in in the sun more often than I remembered and all three survived nicely.

Tomatoes
Indeterminate tomatoes
Most indeterminate tomatoes are simple to overwinter if the frost can be kept off them.  This year was colder than most and I lost most of the tomatoes I had planned to overwinter as I did not look after them all that well.  I grew one seedling far too late  in the season last year so decided to try and overwinter it.  Mid winter, with no heat, just moving it inside at night to avoid frosts the plant started to flower.  The flowers all fell off as it was too cold for pollination to occur but the plant was mature.  This meant that it is easy to plant them out when the weather warms and have them set fruit almost right away.
Tomato plant mid winter
Micro Tom tomatoes
Micro tom is a great little tomato variety that needs more people to grow it and save its seed.  I grew one on the kitchen window over winter to see how it would go.  Apparently they grow just fine over winter if kept inside and this one started to flower when the nights were still frosty outside.  They have such a short lifespan that this particular plant flowered, set fruit and died before Spring came.  What a great plant, while it may not be the tastiest tomato variety it was a lot better than any cherry tomato I could buy from the supermarket at that time if year.  They are not terribly productive but being so small means that it can grow in a tiny pot and not need much space to provide a crop.  Being able to bring them indoors at night means that it is possible to get them to set fruit in Winter, I never would have thought that getting fruit in Winter was possible for a tomato that is not parthenocarpic.

I also planted some Micro Tom seeds mid winter to see if they would germinate in the cold and they did.  Being such tiny plants the kids adore them.  They are even more happy to eat the tomatoes and they tend to carry the tiny plants around talking to them and treating them like pets rather than plants.  The more I grow Micro Tom the more I discover about them that shows me how good they are.

Vietnamese Coriander (Persicaria odorata)
This perennial herb has many, many common names.  It smells a lot like coriander and is far simpler to grow.  It does not bolt to seed like real coriander and does not even flower often outside of the tropics.  It appears to love water and I grow it as a bog plant or an emergent water plant.  It does not like frost, mine got frosted a few times but they all came back in the warmer weather.  Over winter they look terrible, as soon as the warmer weather returned they sprang back to life.  Cuttings strike very easily in water so once it warmed up I cut one plant into many pieces, the original plant grew back and each cutting grew roots within a few days.
Vietnamese coriander leaves turn a bit red in cool weather
Water Celery (Oenanthe javanica)
This is another emergent water vegetable, it is grown for leaves and stems that taste of celery or parsley.  Like many of the vegetables I grow this is a perennial vegetable that rarely flowers or sets seed.  I have the variegated form of this vegetable, while it is prettier than the regular green one it is also not as aggressive in its growth.  I would like to track down the regular green version one day and see just how strong it will grow.  I would prefer a productive vegetable to a pretty vegetable.

My plant grew with no winter protection, the top of the water was covered in ice many times.  It certainly did not love being covered in ice and died back somewhat, the smaller plants that were grown with protection from frost looked a lot healthier at the end of winter.  As soon as the heat returned it was very fast to recover.

Where to get perennial Vegetables
I have been selling perennial vegetable plants and some seeds for years.  Unfortunately we recently moved to town and do not have any land so will not be selling anything for a while.  We do plan on moving again very soon, when we have settled I hope to sell perennial vegetables and vegetable seeds again, they will be listed on my For Sale page when the time comes.

Moving to town


Recently we have moved to town.  We had to sell the property for a number of reasons.  I will miss a lot of things about the property but unfortunately selling was the right thing to do at this point in time.  We are now renting a nice house in town.

Moving to town has been difficult, we have had to sell our animals and alpacas and they are sorely missed.  Our daughters were born in our old house and I developed Immali corn and a few other varieties of vegetables there.  It has a lot of memories and moving was far more difficult than I thought it would be.
In our last few days someone stole our firewood and someone else broke into the mud brick house and cut/took the antenna cables (yet didn't steal anything).  We know who did both of these things but unfortunately can do little about it.  That made moving even harder and more emotional.  I have been praying that I can forgive them, yet I find this very difficult.
Babington's leek bulbils

We have also been very lucky, we asked our new landlord if we could keep two guinea pigs and he allowed us to keep them.  This has made the transition far easier for the kids and they often sit outside holding and patting the guinea pigs.  I think guinea pigs are amazing little animals and very under-appreciated pets.  I should write a post on guinea pigs at some point.

We also asked if we could keep some chickens and the landlord graciously agreed.  I truly appreciate being allowed to keep them.  This has been great as we still have eggs.  It has been many years since we have had to buy eggs and I dread the thought of that ever having to buy them again.  I don't have a rooster so will not be hatching any eggs in the immediate future.
Araucana cross and silkie cross chickens
We took our last two sheep to the butcher and they are now in the freezer so we will not have to buy meat for some time.  I doubt we will be growing our own meat here in any way.  Perhaps I will get some quail or be able to set up a small aquaponics system and raise some edible fish when we move next.

This rental house is very nice and the street is pleasantly quiet, but it does not have a vegetable garden.  I don't understand how people grow food without a vegetable garden.  I am at a loss here.  I guess they pay someone else to grow all their food and simply buy it from a supermarket?  That seems odd to me.  There are so many things that I like to eat which I can not get from a store, other vegetables are so much better fresh.  What I would give for even a tiny plot.  They are a bit precious about grass here so I can only grow things in pots which I have to keep on concrete or pavers in fear of damaging the lawn.
Vegetables but no land in which to plant them
The same vegetables from the other end
Duck potatoes, they grow well in a bucket
I dug up some of most types of vegetables/herbs and brought them here with us.  I could not take many of each, just enough to start again.  Some things do well in containers, others do not.  Many plants have died in the move and many more are looking weak.  I hope that we get to move somewhere with a vegetable garden before many more things start to die.
Micro Tomatoes - unfortunately not all survived the move
Chilli seedlings from rare imported seeds
When I get set up somewhere with a vegetable garden I plan to grow and sell vegetables and seeds again.  I miss having a garden.  I may have some Babington's Leeks and perhaps some other things things for sale soon but can't get too serious or have too many spare plants when growing in pots.  When I do start to sell vegetables again I will list them on my For Sale page.

OSU Blue tomato

I have grown a lot of interesting tomatoes over the past few years, one of the more interesting tomatoes I grew last year was the OSU Blue tomato.  I have had a lot of questions over it so thought I would write a blog post.
OSU Blue tomato
OSU Blue was one of the first high anthocyanin tomatoes, it was bred using conventional methods (ie NOT GM).  In case you were wondering "OSU" is an acronym for Oregon State University.

From what I have read this tomato was developed by Jim Myers, OSU's Baggett Frazier professor of vegetable breeding and graduate students Carl Jones and Peter Mes.  The genes involved in producing the OSU Blue tomato are Aubergine (Abg), Anthocyanin fruit tomato (Aft) and atroviolaceae (atv), these genes came from the wild species Solanum lycopersicoides, S chilense, S cheesemanii, respectively.

This means that, just like every other domestic tomato, the OSU Blue is a complex yet stable hybrid.  I am happy to say that this is a very stable hybrid just like many other types of tomato and seeds are simple to save and they grow true to type.  Being derived from the wild tomato species I had hoped it would be resistant to a bunch of diseases, at this stage I don't know if it is or not.

On a side note I rather like S cheesemanii but they are as rare as hen's teeth in Australia, if you happen to be growing any please talk to me as I would love to get some seeds from you.

The anthocyanin is the same colour that is in eggplants and it is a rich antioxidant.  The fruit ripens to a dark blue/purple/black colour wherever sunlight hits it, anywhere the light does not hit ripens red.  If a leaf or calyx or whatever is on the fruit it gets a shadow of red.  If you were to put a sticker on the unripe fruit it remains red underneath allowing for all sorts of sillyness such as spelling out the names of your kids one letter per tomato.
OSU Blue Tomato, not overly large
 The plants grow and look much like any other tomato plant.  They are indeterminate and grow a regular leaf, the flowers are yellow and much the same as any other tomato.  The leaves and stems may take on a little purple colour if the temperatures are low and the light intensity is high.  When the days get too hot the plant does not colour up as much.  The fruit takes on more colour with low temperatures and high intensity light.  People who grow these to sell seeds on Ebay and such use grow lights to get the fruit to take on more dark colour.  The colour seems to be variable even on the same plant, my plants grew a range of dark to super dark fruits.

The fruit are small, but not too small, about 4cm across.  The dark colour is mainly concentrated in the skin and a little in the flesh just under the skin.  The flesh remains red and the seeds look much like any other tomato seeds.
OSU Blue Tomato
OSU Blue with some skin removed
One question I get about the OSU Blue tomato is about the taste.  If you read about any of the high anthocyanin tomatoes on the Oregon State University web page they sound like they taste absolutely terrible.  In reality they taste ok,  certainly not the greatest tasting nor the worst tasting.  If I had to choose one word to describe the taste it would be "underwhelming".

They tasted slightly better than an average store bought tomato.  Tomatoes from the shops are pretty dreadful at the best of times so this is not a glowing review.  If you are expecting a great tasting tomato because it is home grown then you will be disappointed, other than that they are ok.  It does taste better than other tomatoes I have grown such as apollo (or possibly roma) so are not all that bad.

They lacked any real depth of flavour, they were not very sweet and were not very sour.  They were not overly insipid which was a positive, but they really didn't make a memorable impression on my taste wise.  I have certainly eaten a lot worse tasting tomatoes.
Unripe OSU Blue tomatoes
The blue colour starts long before the fruit is ripe, the unripe tomatoes look very nice while you wait for them to ripen and become edible.  The plant itself is nothing spectacular, it does not crop all that heavily and is not overly robust.  That being said it was not a weak plant and did return a reasonable yield in far less than ideal conditions.

I saved a reasonable amount of seed from my plants and do plan on growing this variety again.  I have a few breeding plans and would love to incorporate the colour into a better tasting, higher yielding variety.  I have seen some people use this to breed a great tasting tomato that has the black/blue skin but is yellow on the inside, I have also read about someone who grew tomatoes that were red and had dark stripes like a tiger.  Lots of fun.  There are many options and I only have so much space/time to pursue them.  We will be moving to town  shortly so I may not be allowed to grow many vegetables for a while.

I have also been asked how OSU Blue Tomatoes got into Australia.  I have no idea how this variety found its way to Australia, it was bred after they closed the doors on the importation of tomato seeds.  Perhaps a university or the CSIRO imported them legally and they leaked out from there, perhaps some private grower or a sneaky large seed company imported them on the sly and was able to evade quarantine (please do not try this).  Perhaps someone or some company payed a small fortune to get the right tests done in order to legally import them.  The person who I got the seeds from initially received them unsolicited from another grower and asked no questions.

I guess I will never know how they got into the country, I also don't particularly care.  Now that they are here I can grow them, distribute them and use them in all kinds of tomato breeding projects.

I may sell OSU Blue tomato seeds, and/or I may breed some new type of high anthocyanin tomato and sell its seeds.  If I do they will be listed on my for sale page along with other annual and perennial vegetables that I sell in Australia.
