Characteristics:

Graceful cinquefoil is a perennial with several spreading to erect stems from 40-80 cm high and fan-like leaves. The herbage is variable, ranging from sparsely to copiously haired. The basal leaves are numerous with petioles up to 30 cm long and the blade usually palmately compound (although it may occasionally be pinnate). The 7-9 leaflets are oblanceolate or oblong-elliptical in shape and 3-8 cm long and with variable leaf margins which range from coarsely toothed with 5-6 teeth per cm to very deeply dissected almost to the midvein. The 1-2 stem leaves are smaller in size and usually consist of fewer leaflets.

The inflorescence is a many-flowered, often flat-topped cyme. The sepals are lanceolate to ovate-lanceolate with pointed tips and are 4-10 mm long. The 5 petals are yellow and obovate-obcordate in shape. They are slightly to considerably longer than the sepals. There are usually 20 stamens and the pistils are numerous.
