An Extreme alpine dwarf, or cushion plant, Smooth Douglasia can be found on moist coastal bluffs, but is much more common growing in the rock wash of the high alpine zone. This makes it an ideal specimen for any rock garden or problem site where soil is sparse. Its flowers are about 1 cm wide, crimson to deep-pink in color, fading to lavender by the end of their cycle. Smooth Douglasia very closely resembles another cushion plant, Spreading Phlox (Phlox diffusa). The name, Laevigata, refers to its small smooth leaves.
