Phenology: Flowering Mar–Jun.
Habitat: Pinyon-juniper woodlands, sagebrush and other shrub communities, open deserts, dry washes and flats, waste places, streambeds, roadsides, sandy areas, rock slides, stony slopes

Discussion
In subsp. lasiocarpum there is considerable variation in the density and location of trichomes on the fruit valve; in some populations (e.g., Rollins & Munz 6741, GH), the trichomes are present over the entire valve; in others they are restricted as a fringe along part of the fruit margin.
