The genus Sedum has some amazing plants. There are tall ones, short ones, some that spread lots, some not to much. All are tolerant of the heat and drought once established. Then the plant breeders got involved and now we have even more plant habits , foliage types, colours and flower colours. Just pick your size and colour, and Sedum probably has it. It may not be hardy in this area, but many are.
Sedum sieboldii is a great little creeper, with blue-green foliage to send your decorating down that interesting path of hues. If you see flowers, they will be a charming pale pink. This probably is not hardy here in Ontario since we are zone 5. Great in containers. Full sun.
