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.
This succulent is excellent in full sun planters where drying out is a problem. A cousin to the garden sedum, 'Lemon Coral' has the same sturdiness, just not the winter hardiness, rated to zone 7 (and we are zone 5). Vivid mounds of chartreuse foliage stay dense, bushy and bright all summer long. Just imagine the combinations with this texture and colour. Best in sunny spots.
Bloom time - probably not
