Yeah, I wasn't thinking about ID when I took this shot yesterday. Sorry, Margot; it's the only shot of it I took.
After a deep(er) dive on Wikipedia, I think there's a good chance it's Rusty-haired saxifrage (Micranthes rufidula). Would you agree?
I agree there is a good chance the flower in your photo is Micranthes rifidula and there is quite a concentration of that species in the Victoria area. The only way to be sure is to look at the whole plant and see if it conforms to the description in E-Flora BC - E-Flora BC Atlas Page . It's very attractive, isn't it?
Could not agree more, Margot. The deep burgundy of the underparts (sorry, vocab is a bit limited here) really set off the bright white petals.
