Dasiphora fruticosa (L.) Rydb. ssp. floribunda (Pursh) Kartesz
Shrubby cinquefoil, golden hardhack, bush cinquefoil
Shrubby cinquefoil is native to temperate and subarctic regions of the northern hemisphere.
Plants: 4–39″ (10–100 cm) tall. It is a densely branched, shrub with erect branches. (D. fruticosa ssp. floribunda is shrubby, while D. fruticosa (or D. fruticosa ssp. fruticosa, depending upon which taxonomy you accept) is more often prostrate.) Bark is peeling on older stems.
Leaves: Pinnate, alternate, about 1″ (2.5 cm) around, divided into 3-7 (usually 5) leaflets. Leaves have short stalks (petioles). Leafelts are linear-oblong, ⅛–¾″ (3–20 mm) long, dark green on top and silvery below, both surfaces covered with fine hears.
Flowers: Yellow, ¾–1½″ (1.9–3.8 cm) in diameter, with five round partially overlapping petals. Flower centers have 15-25 stamens with yellow anthers, and many carpels. They may be single or in small clusters. Stamens turn reddish as they age. Flowers appear from Summer to early Fall.
Fruits: Capsules containing hairy seeds.
Habitats: Full sun, and somewhat moist sandy or rocky calcerous soil.
