Sedum 'Red Cauli' is a stonecrop with burgundy-tinged leaves that carries pink flowers late in the season. The blooms and foliage deepen quickly toward ruby from late summer into fall, so the planting warms in color just as most of the border is fading. The tag lists full sun to mostly sunny and a height of 8 to 12 inches with plants set 12 inches apart.
Like most stonecrops it stores water in fleshy leaves and wants sharp drainage more than anything else; heavy, wet soil is the usual cause of failure. It works at the front of a border, between stepping stones, in rock gardens, and in containers or hypertufa troughs. Bees and butterflies visit the late flowers. Leave the dried flower heads standing through winter and trim them back in spring, and divide or take stem cuttings in spring, which root readily.
Root rot
Plants wilt, yellow, and stunt even in moist soil; lower stems and roots turn brown, soft, and mushy and the plant may collapse. Most common in heavy, wet, or poorly drained ground.
Improve drainage and stop overwatering, and never plant too deep. Lift and destroy badly affected plants along with the soil around the roots. Grow in raised or free-draining beds to prevent it returning.
