I wondered about the wonderberry, and now I know.
Blech.
I wasn’t going to be happy until I had tried them myself, but feel free to take me at my word: this is one strange tasting fruit. Throughout the season I have popped one in my mouth from time to time thinking maybe I just hadn’t caught them at the right stage of ripeness, but at this point I think I’ve spit enough out onto the ground to officially give up. No me gusta.
My understanding is that these are now going to spring up all over my yard, meaning either battle or acceptance. These are the sacrifices we must make for science.

I have something that looks like that in my garden too – but I was told they’re poisonous. A member of the nightshade family which should be left for the birds – not that they have much interest in them!
Please be careful if you choose to eat them…
Thank you, Jesska. Absolutely, people shouldn’t eat anything they’re not sure they can identify. What I planted is solanum burbankii, which I purchased from Baker Seeds: http://www.rareseeds.com/wonderberry/. They are a member of the nightshade family, but so are tomatoes :). The green berries are indeed poisonous, but the ripe berries are suitable for eating. I’m just not sure who would want to :).
