Dasiphora fruticosa

It grows to tall, rarely up to . The habit is variably upright to sprawling or prostrate, but stems are often ascending especially those stems with many long branches. The bark of older stems is shreddy with long thin strips. The plants are densely leafy, the leaves divided into five or seven (occasionally three or nine) pinnate leaflets. The leaflets are linear-oblong, long, with entire margins and more or less acute ends. The foliage (both leaves and young stems) is pubescent, variably covered in fine silky, silvery hairs about 1 mm long. The flowers are produced terminally on the stems and are cm across, buttercup-shaped, with five petals and 15–25 stamens; the petals are pale to bright yellow (orange to reddish in some western Chinese populations). The fruit is a cluster of achenes covered with long hairs. The species is variably dioecious or bisexual; flowering is typically from early to late summer. It is normally found growing in moisture-retentive soils in swamps and rocky areas. The plant is usually only eaten by wildlife when other food sources are scarce, but the leaves of the plant may be boiled to make a tisane called kuril tea. ==Taxonomy==

Sources vary in the number of infraspecific taxa accepted. , the Germplasm Resources Information Network (GRIN) accepts two subspecies: Northern Europe (scattered, in Estonia, Great Britain, Ireland, Latvia, and Sweden) and northern and central Asia. • Dasiphora fruticosa subsp. floribunda (Pursh) Kartesz (syns. Potentilla floribunda Pursh., Dasiphora floribunda (Pursh) Raf., Pentaphylloides floribunda (Pursh) A.Love)). Described from Canada, New York, and New Jersey, North America. Asia, southern Europe (Spain east to Bulgaria), and North America. , Plants of the World Online does not recognize Dasiphora fruticosa subsp. floribunda, but does recognize a variety distinct from Dasiphora fruticosa var. fruticosa: • Dasiphora fruticosa var. veitchii (E.H.Wilson) Nakai (syns Dasiphora veitchii (E.H.Wilson) Soják, Potentilla arbuscula var. veitchii (E.H.Wilson) Liou, Potentilla veitchii E.H.Wilson), native to China (Sichuan, Yunnan) Numerous other varieties have been described from Asia, some of which have not yet been published under the genus Dasiphora, and others in that genus only as distinct species. These include Potentilla fruticosa var. albicans Rehd. & Wils., P. f. var. arbuscula (D.Don) Maxim. (syn. Dasiphora arbuscula (D.Don) Soják), P. f. var. dahurica (Nestl.) Ser. (syn. Dasiphora dahurica (Nestl.) Komarov), P. f. var. pumila J.D.Hooker, P. f. var. mandschurica (Maxim.) Wolf (syn. Dasiphora mandshurica (Maxim.) Juz.), and P. f. var. unifoliolata Ludlow (syn. Dasiphora unifoliolata (Ludlow) Soják). The varieties D. f. var. monticola Rydb. and D. f. var. tenuiloba Rydb. have been described from western North America, but are not widely accepted as distinct. ==Cultivation and decorative uses==

Shrubby cinquefoil is a popular ornamental plant in temperate regions. Different cultivars are variable with flowers ranging from white to yellow, orange and pink, but they are all hardy plants that produce flowers for much of the summer. The flowers are always small, flat, and round, but there are many dozens on each bush. It is very often used by cities and businesses for landscaping because of its hardiness and low maintenance. It was introduced into cultivation in the 18th century, but many of the modern cultivars, particularly those with orange or red flowers, derive from collections by Reginald Farrer in western China in the early 20th century. ==Cultivars==
