Pacific stonecrop or spreading stonecrop has a north to south distribution from Alaska to northern California. The only province or state it occurs in that doesn't border the Pacific Ocean is Alberta, where it is a rare plant only found in Jasper National Park (as of 1985, perhaps it has been found elsewhere in the province since). It is also a rare plant in California. I photographed it along the rocky bluffs off the Onward Point trail near Sandspit in Haida Gwaii, in the same locality as Dave Ingram's image on E-Flora BC: Sedum divergens.
In British Columbia, it is relatively widespread but most closely-associated with the Coast-Cascade Mountains. Habitat-wise, Sedum divergens is associated with rock: rock cliffs, rock ledges, talus slopes, and lava fields. Elevations range from sea-level (like today's photograph) to montane environments at 2300m or 7500 feet.
The succulent leaves of Sedum divergens continue to be used as an early springtime food by some of British Columbia's First Nations. Carla Burton's 2012 doctoral thesis: Wilaat Hooxhl Nisga'ahl [Galdoo'o] [Ýans]: Gik'uuhl-gi, Guuń-sa ganhl Angoogaḿ (Using Plants the Nisga'a Way: Past, Present and Future Use) (PDF, see page 96) details how members of the Nisga'a people use "t'ipyees" or lava berries.
