My kids planted some "Oregon Dwarf" green podded snow peas this year. The packet claimed that they would be ready to harvest in 14 weeks, my experience was not even close to this time frame.
Each of my children has their own little vegetable garden in which they can plant anything they want within reason. They each chose a few vegetables to plant and were also allowed to grow a few flowers if they wished. We grow everything from seeds, I don't see the point of buying seedlings.
My kids all love snow peas, so this year I bought a packet of 'Oregon dwarf' snow peas and my kids planted some each. Normally we would have planted seeds that I have saved but this year after moving the seeds were still packed in a box somewhere so we bought some seeds.
These snow peas were green podded, white flowered, and reasonably productive over a short period. They possibly could have been more productive over a longer period but were probably planted a bit late, but we could not plant them any earlier due to the kid's gardens not being ready to plant prior to this date.
The following were the days to maturity for snow peas my children planted in 2016. Being in Australia all of the dates are written as Day/Month/Year
Oregon Dwarf Snow Pea Days to Maturity

Germinated Day ?
Flowering Day ?
Harvest began 06/12/2016 Day 42
As these were in the children's vegetable gardens I did not keep as many stats as I normally would. The date planted may have possibly been the date germinated, I am not entirely certain. Regardless, this is pretty fast, this is actually a lot faster than I would have expected. It was only 6 weeks as opposed to the 14 weeks as claimed on the packet. Perhaps the days to harvest were less as I planted them in warmer weather than normal.
