Blue Spruce Sedum (Sedum rupestre 'Blue Spruce'): Conifer-Like Groundcover

Overview

Blue Spruce Sedum (Sedum rupestre 'Blue Spruce', syn. S. reflexum) is a low, mat-forming sedum with needle-like, blue-gray leaves that resemble a miniature blue spruce. The leaves are arranged around the stems in a spiral. In early summer, bright yellow star flowers cover the mat. It spreads quickly to form a dense, weed-suppressing carpet 4–6 inches tall. The foliage may take on pink tones in winter. Extremely tough, drought-tolerant, and cold hardy. Ideal for rock gardens, green roofs, walls, and containers.
