Hi Lynn
It's not actually my plant. I saw these in a garden centre. I always photograph things that take my interest.
I would imagine it likes conditions for other ground cover sedums. It will grow in well drained soil in zones 4 - 9 and requires modest watering except maybe in summer. It has yellow flowers but I think it would look good planted against a light background or companion as it's a dark leaved plant.
Good luck with it!
Sue
