Wonderful thread with very useful info about saving/replanting peas!
I have planted a bunch of different varieties this year, some of which were saved at least two years or more ago. I soaked overnight and they all appeared to be viable.
Yakoma Giant is a very large snow pea with purple flowers iirc and reddish brown seeds. They were planted late last time and didn't produce many before the end of season, so I'm really hoping my few seeds will come on so I can save more this time. We often have wet cold weather at the end of season so it's great to have the option of drying them out of pod if mildew is a present threat. Also planted lots of Golden Sweet which is a personal favorite, they produce over such a long season. I have a row of Norli which were saved in 2014 - there were a couple left over and they quickly put on longer sprouts so it seems they kept fine even for five years.
And I have a few Blue Bantam, Early Frosty and Little Marvel put in, from swap (undated) but looking alive.
Bigger question now is whether the continuing cold and wet weather will do any harm. I sure hope not! I read somewhere that the red/brown seeded peas, which have colored flowers, are also more tolerant of planting in cold soil. That would be a big incentive for me to save and maintain those varieties, as cold and wet is much the rule.
I have a few more types of peas that I may find a spot for before I'm done, mostly old commercial source peas which I had doubts would be still viable.
I think I'll soak first just to see if there's a sign of life. I don't even know how old they are anymore.
