Resilient, fast-spreading, and wildly adaptable, Sedum reflexum is the groundcover that refuses to be ignored. With its needle-like, blue-green foliage, this low-growing, mat-forming succulent brings a sharp, textural contrast to rock gardens, borders, and dry landscapes. But when summer rolls in, it explodes into clusters of bright yellow, star-shaped flowers, turning into a pollinator paradise buzzing with bees and butterflies. Whether cascading over a stone wall, filling in a tough, dry patch, or spilling from a container, this drought-proof, cold-hardy sedum never quits.
