Sedum treleasei is a succulent plant with pale blue-green, thick and fleshy leaves up to 1.5 inches (3.8 cm) long, somewhat flattened on top and rounded below. Older leaves often take on a yellow tinge at the tips and margins, and sometimes there is a flush of pink on the leaf tips. Plants develop stems which may reach up to 1 foot (30 cm) in height, and they branch to form a good-sized clump in time. Flowering commences at the end of February or in early March, and extends into April. The flower stalks are up to 6 inches (15 cm) long, adorned with bracts which are miniature replicas of the leaves. Each stalk ends in a cluster of bright yellow, star-like flowers up to 0.5 inch (1.3 cm) across. Native to Mexico.
