Taxonomic Rank: Magnoliopsida: Rosales: Rosaceae
Synonym(s): sulphur cinquefoil, roughfruit cinquefoil
Native Range: Temp. Asia & Europe (GRIN);

Appearance
Potentilla recta is a perennial herb that can grow to 19.7 in. (50 cm) tall. It is native to Africa, temperate Asia and Europe.
Foliage
A loose rosette of long-petiolate leaves develops first and withers before flowering. Plants can be one or multi-stemmed. Stems are covered with long and short hairs and are unbranched. Cauline leaves are palmately compound (with 5-7 leaflets), stipulate and short petioled to sessile. The central leaflet is 1.2-5.9 in. (3-15 cm) long (longer than the other leaflets).
Flowers
Flowering occurs from May to July, when sulfur yellow flowers develop in open, flat-topped inflorescences at the apex of the stems. Flowers have 5 petals, each 0.2-0.4 in. (0.5-1 cm) long, and 25-30 stamens.
Fruit
Fruits are small, dark brown achenes with pale veins. Seeds often have a webbed or net-like pattern on them.
Ecological Threat
P. recta occurs in pastures, rangelands, along roadsides and other disturbed sites. NOTE: The native graceful or slender cinquefoil, P. gracilis has short hairs that lie flat on the stems and leaves and brighter yellow flowers than the invasive P. recta.
