Location: Almont Triangle, GV, CO
Life Zones: Plains to montane
Habitat: Dry sandy, rocky slopes, disturbed areas

Grows low to the ground from a basal rosette of narrow, irregularly toothed or lobed leaves. Flowers are large, to 4" across, and fragrant, and grow with a long floral tube resembling a stem from the rosette (tuft). Buds point upwards. Flowers open in the evening then wilt and turn pink in the sun.

There are 5 subspecies of the Tufted Evening Primrose which are differentiated by differences in their seed capsules, length of floral tube, and shape and hairiness of the leaves. Below are two more that are unidentified, by me.
