Semi-evergreen in mild winter areas.

Noteworthy Characteristics

Potentilla neumanniana, commonly known as spring cinquefoil, spotted cinquefoil or alpine cinquefoil, is a vigorous, procumbent, mat-forming, herbaceous perennial of the rose family that typically grows in dwarf, horizontally-trailing form to only 2-4” tall spreading to 12” wide or more. It is native to Europe. It features 5-7 palmate, deep green leaves and 5-petaled buttery-yellow flowers (1/4” diameter). Flowers bloom in loose clusters (3-5 flowered cymes) in April-May. This plant is one of the first of the cinquefoils to bloom in spring. Decumbent rooting stems (to 5” long).

Formerly known under the now considered synonymous names of P. tabernaemontani,P. verna or P. crantzii.

Genus name from Latin potens meaning powerful is in reference to the reputed medicinal properties of the plant.

Common name identifies this plant as being a cinquefoil which typically has 5 petalled flowers and 5 palmate leaves (cinq meaning five in French).

‘Nana’ is a prostrate, mat-forming, slow-growing cultivar which grows slightly shorter (2-3” tall) than the species. Spicy-scented, shiny, palmate leaves are deep green. Abundant yellow flowers appear in spring.
