Spaugh which varieties would you recommend for someone out of the growing zone? I just want fresh dragonfruit!
S8 is a very reliable performer, but it's later, and likes heat, but honestly Brad was right about this for years now. It's probably the only one worth having, the rest are novelty in comparison to how reliable s8 is, and how sweet the flavor is. S8 though is not that cold hardy, so don't leave it outdoors in SC too late.
This said, here is my experience with the varieties I do have.
I have really good luck with Asunta, it is the first to flower, it sets almost every single flower, and the fruit has crazy long hang time... It's just not that awesome of a cultivar, unfortunately. Flavor is meh. I think most all of the purple flowers are "just ok" on flavor.
Cosmic Charlie is good for me as well, reliable, but it's self-sterile. This is a serious drawback. I don't really bother collecting DF anymore, and the only reason I keep this one is that it's my biggest plant and is somehow more cold resistant, and more disease resistant than others.
Purple Haze is good flavor, decent productivity, self fertile, but super prone to rust.
Dark star is great flavor, but productivity is not great. It doesn't grow that well for some reason, maybe my roots have issues dunno.
If I had to pick another one for the list to collect, I would like American Beauty.
I used to be crazy about dragonfruit but have backed off. I will probably break down some of my stands next year and chuck the plants in the woods to die and then re-do them with all S8 (and concrete posts).
