We have an unusual plant on our cliff, it's called Stonecrop. It's unusual because it's a succulent that you would expect to find in a drier climate, but it seems to thrive on the sunny face of our cliff. Surprisingly, in Coastal British Columbia, you can find it clinging to the ground on rocky, exposed outcrops.
I believe ours is Sedum spatulifolium. The leaves are fleshy and sage-green to reddish. In summer, they develop bright yellow flowers on tall stems. Historically, the Coastal Salish people used Stonecrop leaves as a styptic poultice.
Are you interested in plant identification? I use Plants of Coastal British Columbia by Jim Pojar and Andy MacKinnon. It's available from Amazon.com or Amazon.ca. I like it because it includes trees, shrubs, wildflowers, aquatics, grasses, ferns, mosses. lichens and some oddball (and very interesting) plants. In addition to the color pictures, line drawings, and identification information, the narratives include how the plants were used by First Nations people and early settlers. I highly recommend it for the casual observer as well as experienced botanists. -- Margy
