CC = *
CW = 3
MOC = 15
Family - Rosaceae
Habit - Perennial forb with short rhizomes.
Stems - Prostrate, trailing, and stolonlike, to 80 cm, rooting at some nodes, unarmed, hairy.
Leaves - Rosettes at the rhizome tips and where the aerial stems root, otherwise alternate, long-petiolate, trifoliate. Stipules 4-9 mm long, herbaceous, narrowly oblong-elliptic, hairy, those of the rosette leaves fused toward the base. Petioles to 6 cm long, antrorsely pubescent. Leaf blades 1-7 cm long, broadly ovate-triangular in outline, divided into 3 similar leaflets, these 1.0-6.5 cm long, elliptic or ovate, rounded to more commonly pointed at the tip, rounded or narrowed to a short-stalked base, the margins bluntly toothed or scalloped, the surfaces sparsely to moderately appressed-hairy, especially along the veins.
Inflorescences - Flowers solitary in the leaf axils (and among the rosette leaves), long-stalked, each with 5 bractlets beneath and alternating with the sepals, these noticeably wider than the sepals, broadly obovate, prominently 3-toothed or -lobed at the tip, becoming somewhat enlarged and reflexed at fruiting
Flowers - Perigynous, perfect. Sepals 5, 4-7 mm long, usually arched upward, ovate-triangular, sparsely to moderately hairy, somewhat enlarged at fruiting. Petals 5, 5-9 mm long, narrowly obovate, yellow. Stamens 15-25, the anthers yellow. Pistils numerous, densely covering the surface of the obconic expanded receptacle. Ovary superior, glabrous, with 1 locule, with 1 ovule. Style 1 per pistil, attached laterally, shed before the fruit matures, the stigma disc-shaped.
Fruits - Achenes, in a headlike cluster densely covering the surface of the enlarged expanded receptacle, but shed eventually, 0.9-1.5 mm long, asymmetrically ovate in outline, glabrous, shiny, red.
Flowering - April - June.
Habitat - Lawns, forest openings, open disturbed areas.
Origin - Native to Asia.
Lookalikes - Flowers resemble those of Potentilla species. Fruits resemble those of Fragaria species.
Other info. - Anyone who tastes the fruits of this plant is in for a rude 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. Beyond Missouri it also occurs in most of the eastern half of the U.S.
