Stems spreading on ground and forming rather extensive mats below 2-10 deep reddish-pink flowers (aging to lavender) in tight umbels on short leafless stalks.

Douglasia, named for David Douglas, an early-19th-century explorer of western North American plants, are prized rock-garden subjects. The plants need not be dug up, as they grow well from cuttings or seed. The genus superficially resembles Phlox, in which each stamen in the corolla tube is attached in line with the notch between corolla lobes; in Douglasia each stamen is attached in line with the middle of a corolla lobe.
