For a rich blanket of color in those hot, sunny areas, try Sedum 'Firecracker' from breeder Chris Hansen who also brought us 'Dazzleberry' and 'Lime Zinger'. This is a very dense growing, well-branched selection that won't split open in summer. It puts on a strong show of burgundy red color all season long, with only the tiniest new leaves emerging mint green. Plant 'Firecracker' en masse in the landscape as a colorful, weed-suppressing ground cover and enjoy its vibrant pink flowers in late summer to early fall as an added bonus.
Sedums are "plant and forget" perennials. Because of their ability to store water in their thick succulent leaves they are very drought tolerant. They do well in average well drained soil in full sun to light shade. Do not add extra organic material because this will make the plants open and floppy.
