Discussion | Varieties 2 (2 in the flora). Sedum lanceolatum forms offsets in the axils of rosette leaves. The mature carpels have divergent beaks and narrow lips along the adaxial suture. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Variety nesioticum occurs in westernmost Canada and United States, on islands in the Puget Sound and the Straits of Georgia, and adjacent Vancouver Island. The relatively large plants flower approximately two weeks later in the season than do those of var. lanceolatum because the coldness of the adjacent ocean retards flower initiation.
