So this grows a bit like other forest perennials, like wild sarsaparilla it's a low broad leafy plant. the outer part of the pods are supposed to edible, but I didn't try these ones while I was cleaning the seed. the pods break open to expose pea sized seeds in a very pulpy clingy interior. I'll glow a set in the nursery next spring, and should have enough to share some on our seed shop.Read field note +2

I'm fine with the wasps if they keep some distance, they're very attracted to sugar and over ripe fruit, and they have this cool way of hollowing out an apple. it's only a few fruit so I chalk it up to food for wildlife, and I think it's only the fruit that were overripe. I haven't needed to spray any of our fruit trees yet, but I understand that it may be needed eventually depending on the pests to keep everything healthy, we have bee hives on our property and plenty of wild pollinators, and we aren't a commercial orchard, a few spots on the apples are ok just give me the bees.. there's a song about that rightRead field note +1
