Outstanding Qualities

Sedum cyaneum is an excellent groundcover plant, particularly for hot, dry sites with poor soil. This variety forms a flat, dense mat of gray green leaves. Clusters of purple pink flowers appear in late summer into fall. Sedum cyaneum is well suited for the rock garden or edging in a dry border, also a good choice for containers. Sedum cyaneum makes a good companion plant for Eryngium amethystinum 'Sapphire Blue.'
