They are in fact Physalis Pruinosa. I didn't get them from Tomatopalooza but did taste them there. The seed came from Victory. Craig also sent me some and I started those on the 12th becuase I didn't think the first were going to come up.
The first (VICTORY) have so far germinated 5 out of 7 seed. All 5 came up on day 14. I also started 7 of Craig's seed. We'll see if the germination is notable different. Craig's seed are known fresh. He told me they were from this past summers fruit.
Side note I responded a few hours ago but it obviously didn't post.
