detailed seed-starting info below

Forms a low mound, whose wiry stems hold both silver-grey leaflets and spines. Small candytuft-like flowers appear in clusters, and reportedly smell of honey. Sounds like it will be difficult to keep alive, requiring sharp drainage in winter. Native to Morocco and Spain.

We're just trying this plant for the first time this year; it hasn't found a permanent place in our gardens yet. (click here for a full list)
