nostr:npub17az3s5w227nh4hlwh4xjgf4f6xtel2mlm4xwjnch2rtq4fhsp25s295jcv Physalis grisea as a species reaches into Canada (Quebec ground cherry) but I don’t know how far north exactly. My seeds were sourced from the wild in zone 8 but if you would like to try it out, you should find a Canadian source in case there are zone variants in the species. Tradewinds sources their P grisea from Canada. https://www.tradewindsfruit.com/physalis-grisea-quebec-ground-cherry-seeds but you might be able to find other 🇨🇦 sources locally.
do you get cloud berries where you are?
