Wintergreen will prefer shade but kinnikinnick does fine in (actually

supressing weeds, however. It seldom forms dense enough coverage to
prevent weeds from growing through and then you have the added mess of
trying to remove the weeds from the interior of the plant without
damage.

I'll second that. My kinnikinnick is in full sun in Portland and while
it's happy without supplemental watering, it always has grassy weeds
growing up through its middle areas and I wouldn't describe it as
spreading quickly at all. Pretty, though...
