Blue Elf is a striking intergeneric hybrid stonecrop with frosty, steel-blue succulent rosettes overlaid with a hazy plum tint, forming a low mat that erupts into clusters of fragrant, dark pink flowers in late summer. Its unusual foliage color makes it a standout foliage accent in rock gardens, troughs, and border edges even when not in bloom. It is highly drought tolerant and largely ignored by deer.
