Has anyone grown a Marula tree (Schlerocarya birrea)? I have the seeds of some as well as some Jacaranda seeds and would like to try to grow them. I'm in Zone 7b, newly classified as Zone 8, though I take that with a grain of salt, and I'd love to know what sort of conditions they need. I plan to grow them on my roof deck in containers and bring them into the basement in the winter. I'm also growing Elegia capensis in containers on the roof, and I'd love to hear anyone else's experience with this beautiful plant, which I first saw in SA's Kirstenbosch Botanical Gardens.
