I’d suggest planting in an area that’s usually moist. Perhaps limiting the direct sun to 8 hours would help. My wilts during the heat of the day, but bounces back at night. Maybe plant them on the north side of a Hügel mound where there is good moisture. Just my 2 cents worth, I’m no an expert by any means but have learned through experience. I’ve found that it likes areas by water or wet areas. Planting in heavy mulch is also helpful by holding moisture underneath. Good luck! Oh, and don’t fertilize it or plant in good soil. It does better in junk soil, rocky or clay soil – definitely not in potting soil.
