Flowering - April - June.

Habitat - Lawns, forest openings, open disturbed areas.

Other info. - Anyone who tastes the fruits of this plant is in for a surprise. Despite their luscious appearance, the fruits are dry and insipid and nothing at all like a real strawberry. As of early 2019, this introduced species has been reported from 15 counties in Missouri, up from the 4 counties reported in Steyermark's 1963 publication. It is likely to be more common than collections indicate.

The species is easily recognized by its prostrate habit and yellow flowers. It is particularly tolerant of mowing and is often found in lawns.
