Sedum ternatum; Crassulaceae (stonecrop family)

A low-growing plant, one of very few in this area with succulent leaves.  The leaves occur in whorls of three along the stems.  The flowers appear in a three-branched terminal cluster.    It’s related to some familiar garden plants, like hens and chickens (Sempervivum tectorum) and sedum “Autumn Joy” (a hybrid of Sedum spectabile and Sedum telephium), which is used extensively in landscaping.

I do wish more people would garden with native plants.  This low-growing stonecrop would make a nice edging along a rock wall or pathway.  The flowers are small and subtle, but quite fetching when you look closely:

I love small, subtle things.
