Sulphur cinquefoil is a perennial herb that can grow to 19.7 in. (50 cm) tall. 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 (branched only in the inflorescence). Cauline (stem) 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). 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. (6-9 mm) long, and 25-30 stamens. Fruits are small, dark brown achenes with pale veins. Sulphur cinquefoil is native to Europe and occurs in pastures, rangelands, along roadsides and other disturbed sites.
