Harpagophytum procumbens- Devil's Claw(African)

Hi there,

It's my first post here, after reading a bunch this year about more than I can mention in one post.

Straight to the question- has anyone grown devil's claw(Harpagophytum procumbens) in the US, but really anywhere outside of Africa?

Things I know after my own inquiries to Mr. Google and experience w/ this plant( not a complete list of my knowledge, hopefully)-

-It probably would have happened in a container, but not necessarily.

-Plants are native to South Africa

- They're hard to cultivate and protected in the areas they naturally grow.

- VERY little info on growing conditions online, from what I can find, though super welcome to any suggestions at all.

- Sandy soil, dry climate, geophyte(tubers), etc...

- Most folks are familiar because of herbal uses for joint pain, headaches, arthritis, possible blood pressure control, etc...


Bottom line- I'd like to talk with anyone who has actually successfully grown this in the US, any region. I've had first hand healing experience with the herb and would like to grow it in a sustainable(kinda) commercial setting, probably in a large container with geo thermal help from the buildings on the property.

Thanks in advance!
