A Eurasian introduction, first collected in 1976 in Berrien Co., and now a weed of lawns, driveways, trailsides, gardens, fallow fields, campgrounds, and other disturbed sites.

The petals in our material of both this species and C. flexuosa clearly exceed the sepals, unlike noted in some descriptions of the species. 

This species is now a characteistic plant of dry, sunny lawns and similar open grassy sites in some areas, flowering with short, often few branched stems and conspicuous basal rosettes as early as late March, or even earlier during warm spells in late winter.
