I have a friend that has a hill in her yard that is full or rounded boulders and smaller rounded rocks. There is a rocky, sandy dirt between some of them. She asked me for suggestions for plants, so I'm asking here! I'm thinking sedums and hens and chicks, but I'm sure there's more types of plants that would do well there. This is zone7b, the site is in full sun, and has rapid drainage. Thanks for your help!
