Columbia Gorge daisy is a pretty wildflower of Columbia River cliffsides. Its herbage is both glandular and loosely sticky-hairy. The stems are lax, ranging from 5-15 cm long, and arising from a tuft of basal leaves. The basal leaves are obovate to spatulate, coarsely toothed at the distal ends. They are up to 9 cm long and 2.5 cm wide. The stem leaves are well-developed and may be ovate, elliptic or lanceolate in shape, from 4 cm long to 1 cm wide.
The inflorescence is leafy, consisting of one to several heads. The disks are 9-13 mm wide, surrounded by 30-60 white, pink, or bluish rays. Individual rays are 5-8 mm long. The involucres are 5-7 mm tall, with loose, thin, and green bracts.
Columbia Gorge daisy is usually found on moist shady cliffs and ledges.
Columbia Gorge daisy is only found in the Columbia River Gorge between the elevations of 100'-1200' between Crown Pt and Mosier, OR. It is primarily found on the Oregon side of the river, which has a moister, shadier habitat.
