Definition
Anemone multifida is a perennial herbaceous plant species belonging to the family Ranunculaceae. It is commonly referred to as the cutleaf anemone or mountain anemone.
Overview
Native to western North America, Anemone multifida occupies a range that extends from the Pacific Northwest through the Rocky Mountains down to California and into parts of the southwestern United States and northern Mexico. The species typically thrives in montane and subalpine habitats, favoring moist meadows, stream banks, and open forest clearings at elevations ranging from 1,200 to 3,500 meters. It blooms in late spring to early summer, producing conspicuous white to pale pink flowers that attract a variety of pollinators, including bees and flies.
Etymology/Origin
The generic name Anemone derives from the Greek word anemos meaning “wind,” alluding to the plant’s delicate, wind‑shaken appearance. The specific epithet multifida is Latin for “many‑cleft” or “deeply divided,” describing the plant’s finely dissected, lobed leaf morphology.
Characteristics
- Growth habit: Perennial, herbaceous; stems arise from a deep, branched rhizome. Stems are erect, typically 10–40 cm tall, and may be sparsely branched near the apex.
- Leaves: Basal leaves are palmately divided into numerous narrow lobes, giving a feathery or “cut” appearance. Leaflets are linear to lanceolate, often with a toothed margin. Upper stem leaves are reduced and may be sessile.
- Inflorescence: Typically a solitary flower per stem, though occasional cymes occur. Flowers consist of 5–7 petaloid sepals (no true petals), each 1.5–2.5 cm long, and numerous stamens central to the floral cup.
- Fruit: The plant produces an achene—a small, dry, one‑seeded fruit—encased in a silky, persistent style that aids wind dispersal.
- Phenology: Flowering occurs from May to July, varying with altitude and latitude. Seed maturation follows shortly after pollination, with dispersal occurring in late summer.
- Ecology: As a member of early‑successional meadow flora, A. multifida contributes to soil stabilization and provides nectar resources for pollinators. It is tolerant of cold temperatures and can persist in areas with seasonal snow cover.
