Description

Sticky Cinquefoil is a one to two foot tall perennial with creamy yellow flowers. It has soft pinnately compound leaves and red stems. It is a highly variable perennial forb. Erect stems arise 4 to 24 inches (10-60 cm) from a loosely branched caudex. The mostly basal leaves are pinnately compound and sharply serrate. Leaves and stems are glandular pubescent. Flowers are few to many in a flat-topped cyme. Fruits are glabrous achenes.

Bloom Period

Distribution

Western N. America.

Habitat

Ecological Setting Sticky cinquefoil occurs in a wide variety of habitat types Soil Texture Medium textured, well-drained loam Light (sandy), medium (loamy) and heavy (clay) soils and requires well-drained soil. Shade Tolerance Intermediate shade tolerance. It can grow in semi-shade (light woodland) or no shade. Prefers a position in full sun, but tolerates shade Successional Status Sticky cinquefoil is an early-seral, shade-intolerant species that establishes and/or increases following fire, logging, and grazing. Sticky cinquefoil is not a common component of mature forest vegetation. However, it can persist on old fields for several decades after abandonment. Sticky cinquefoil was prominent the 1st and 2nd year following logging on ponderosa pine-pinegrass-elk sedge (Pinus ponderosa-Calamagrostis rubescens-Carex geyeri) sites in eastern Oregon. It was not abundant prior to logging. Sticky cinquefoil increased in the first 5 years after clearcutting in a northern Sierra Nevada stand dominated by Pacific ponderosa pine (P. ponderosa var. ponderosa) on the Challenge Experimental Forest. It was not stated whether it was present in the stand before logging.
