Herbaceous, rhizomatous perennial; leaves all basal, trifoliate, on long petioles; leaflets broadly cuneate-obovate, serrate and usually shallowly lobed, the lateral leaflets asymmetrical; inflorescence a cyme with few to several flowers; peduncle about equaling the leaves; sepals triangular; hypanthium obconic, its mouth contracted by a conspicuous disk; petals yellow; stamens numerous, the filaments slender, erect, persistent; carpels 2-6, free and distinct, inserted on a hairy receptacle, mostly enclosed by the hypanthium but with the styles protruding; ovule 1, basal; fruit an achene.

Notes

Flowers early May to late June

Wetland indicator: NA

This plant resembles strawberry (Fragaria spp.), hence the specific epithet fragarioides. It is called Barren Strawberry because it does not produce a fleshy fruit, rather a head of dry achenes. Interestingly (to me anyway), this species is absent from the Chicago region, yet common in forests of central NY.
