Sedum palmeri

A succulent perennial native to northeastern Mexico, it forms branching stems tipped by rosettes of fleshy blue-green leaves. Clusters of bright yellow star-shaped flowers rise above the foliage, each with five pointed petals and spreading stamens. Older stems may trail or hang downward over rocky surfaces. Leaves can turn reddish-pink in strong light or cold weather. It flowers in spring. Photographed in Colombia.
