Remarkable form and bold coloring make this English variety a standout in perennial gardens, floral displays and containers. Growing 18–24" tall, the Carl Sedum has a more compact habit than the Autumn Joy Sedum. It distinguishes itself with the large clusters of brilliant, magenta-pink flower heads that grow on its reddish stems in late summer and early fall. The rounded, slightly serrated, gray-green leaves form a densely mounded, upright clump. Also called a stonecrop, this sedum provides color when many perennials are fading into fall. This drought-tolerant perennial needs well-drained soil and a nice sunny spot in the garden. It attracts bees and butterflies.
