Potentilla Identification Guide

Key Identifying Features

Shrubby potentilla, or cinquefoil (Potentilla fruticosa, syn. Dasiphora fruticosa), is a small, twiggy, deciduous shrub that blooms for months with abundant flat, five-petaled flowers resembling little wild roses or buttercups, most often bright yellow (also white, cream, orange, or pink in cultivars). It forms a dense, rounded mound 1-3 feet tall with small compound leaves of narrow leaflets. (Note: many herbaceous Potentilla species exist too, but the common garden shrub is P. fruticosa.)

• Five-petaled, saucer-shaped flowers with many stamens, blooming all summer
• Small palmately compound leaves, usually 5 (3-7) narrow leaflets
• Dense, mounded twiggy shrub
• Shreddy reddish-brown bark

Leaves & Stems

Leaves are alternate and palmately (or pinnately) compound, with 5 (sometimes 3-7) small, narrow, oblong leaflets, each about 1/2-1 inch long, gray-green to bright green, often with a slightly silky or hairy surface and inrolled margins. 'Cinquefoil' means 'five leaves', referring to the typical five leaflets. Stems are slender, much-branched, and clothed in thin, shreddy, reddish-brown bark that peels with age. The fine-textured foliage on a low mound is distinctive.

Flowers & Fruit

From late spring through frost, potentilla is covered in flat, round flowers about 1 inch across with five rounded petals and a central boss of many yellow stamens—structurally like a single wild rose (it's in the rose family). Wild and most common forms are buttercup-yellow; cultivars add white, cream, gold, apricot, and pink. The long, nonstop bloom is a key trait. Fruits are tiny, dry, brownish achenes in a small cluster—no showy berries.

How to Tell It Apart from Look-Alikes

• Cinquefoil weeds (herbaceous Potentilla): similar five-petaled yellow flowers but low creeping herbs, not woody shrubs.
• Buttercups (Ranunculus): glossy yellow five-petaled flowers but lobed, not compound, leaves and herbaceous stems.
• Shrubby St. John's wort (Hypericum): yellow flowers but opposite simple leaves and bushy stamens differently arranged.
• Rock roses (Helianthemum): five-petaled but simple opposite leaves.

The woody mound + small 5-leaflet compound leaves + nonstop five-petaled flowers confirm shrubby potentilla.

Where You'll Find It

Potentilla fruticosa is native across cool-temperate and subarctic regions of the Northern Hemisphere (North America, Europe, Asia), growing in meadows, rocky slopes, and moist tundra. It is extremely cold-hardy and is widely planted as a low, long-blooming foundation, border, and mass shrub in full sun and well-drained soil.

Quick ID Checklist

• Low, dense, twiggy deciduous shrub, 1-3 ft
• Small palmate leaves with ~5 narrow leaflets
• Five-petaled flat flowers (yellow most common), all summer
• Many stamens in the flower center (rose-family look)
• Shreddy reddish bark; no berries
