Howell's daisy is a very pretty perennial wildflower often found in clusters of plants with several stems rising from a rhizome. The stems range from 20-50 cm in height. The leaves are thin, smooth, and a shiny green, with the lower ones elliptic to suborbicular, with the blade abruptly contracted to the 2-12 mm petiole. The lower leaves range from 2-8 cm long and 1.5-4.5 cm wide. The stems are many-leaved, with the leaf bases clasping. These leaves are ovate to cordate in shape.
The flower heads are solitary at the tips of the stems. The yellow central disks measure 12-20 mm wide, and 30-50 white rays surround the circumference of the disk. Individual rays are 13-25 mm long and 2-4 mm wide.
Erigeron howellii is closely related to Erigeron peregrinus.
Howell's daisy is found in moist, rocky places.
Howell's daisy is found only in the Columbia River Gorge. It is found on the Oregon side of the river between Angels Rest and Wind Mt. between the elevations of 200'-4000'.
