When we moved here I dug up the leeks and brought them with us. Normally they keep growing as usual but this summer they seemed to die down to bulbs which made moving easier. I planted them out in one of the vegetable gardens. The picture below shows some of the leeks I have planted.
|Perennial leeks - very hardy|
As all leeks apparently do, they grow rather slowly. But these ones multiply fast. I have let some plants flower but they have never produce viable seeds for me. By the time a large leek is ready to be dug up and eaten it will have numerous smaller leeks ready to take its place. If you divide the babies off they all grow large and start to multiply, if you do not divide them they keep growing but are much smaller.
The picture below shows a larger leek in the background, with many smaller leeks in the foreground waiting to be divided. As you can see the lack of viable seed is not a problem whatsoever.
Like all the vegetables that I have got online I had hoped that these would do well and would eventually pay for themselves in one way or another. Some things have paid for themselves by reducing the amount of groceries we have to buy, others such as yacon pay for themselves by being sold. The leeks certainly have been hardy and generous plants and have grown and multiplied well. After seeing the prices for leek in the supermarket I know that they have paid for themselves several times over just from what we have eaten.
Since writing this I have grown some regular leeks and have written a post comparing these with perennial leeks here
I do sell perennial leek plants as well as some other perennial vegetables, herbs and some vegetable seeds, please see my For Sale page for details.
