Shrubby Cinquefoil, Potentilla fruticosa L.
Rosaceae

Erect, dense, scrubby looking shrub, 0.2-1.3 m high. Older bark is reddish-brown and shreddy. New branches are light reddish-brown and densely hairy.

Buds: About 6 mm long and brownish, covered by persistent raised leaf scars and stipules. Bud scales are papery and dry, the outer scales barely covering the inner, pre-formed leaves.

Leaves: Alternate and crowded on the stem. Pinnately compound with 5-7 leaflets, 1.3-2.5 cm long, narrowly oblong to lanceolate and sharp-pointed. Both surfaces have white, silky hairs. The undersurface is whitened and densely hairy.

Flowers: Solitary, or in few-flowered clusters, each bright yellow, 1-2.5 cm across, with five rounded petals and 15-20 stamens. Blooms from early July to mid-September.

Fruit: Consists of many small seeds clustered to form dense heads about 6 mm across, enclosed by persistent calyx lobes. They remain throughout the winter.

Habitat: Wet places – fens, shores of ponds and brooks, edges of woods, wet heaths, roadsides. Less common on dry rocky barrens and limestone talus. Found throughout Newfoundland and southern and central Labrador.
