I had it growing in a spot on top of a rocky marly scree, I added a bit of DG and compost but it was mostly limestone chunks. There was a bit of shade in the morning and then maybe late afternoon. It was sold as S ambigua but I think it was S incase. I had the S. ambigua also. I can't keep them straight and I think the growers can't keep them straight either. I see them miss labeled a lot , so often , that I can't keep them straight. It died ion the big drought. I re planted it but the dear have it on their menu now. . I am shopping for some more to put under the fragrant mimosa. I am hoping the thorny branches keep the deer at bay. One of my defensive gardening techniques. I have a lavender flowered one. I had it at the swap but know one took it so I planted it under the mimosa. here are some pictures from several years ago. They are getting ready to bloom with means that the deer will be through my garden anyway now.

They are in the midgound behind the Spanish lavender.Looking at this, I need to tear everything out and start all over. Things look so much better here then than now.
