Hardy Chili (Capsicum flexuosum)

[ImGrimmer]

Anyone have experience with Hardy Chili (Capsicum flexuosum)? It is supposed to be cold hardy. Can anyone confirm this?

My only experience is not being able to germinate it and having cuttings of it die in the post. Will be giving it another go this year so will report back.

This chap is planning to test it this outside this winter in the UK I believe: https://radix4roots.blogspot.com/

Intriguing. Does it hybridize with common peppers?

I think it can cross with chinense and annum, few others pretty easily. It also has some self incompatibility issues which could be used for breeding projects.
 Offspring won't be as hardy unless you do a bunch of backcrosses. Still extends season.

Very interesting. Might add this to my wish list.

I don't think the species itself is that amazingly hardy, but as you said, it could extend the season a little, by helping them resist late or early frost (or near-frost). This alone can potentially add about 20% growing days around here, on a not so atypical year.
