- Name also: Snowdrop Windflower
- Family: Buttercup Family – Ranunculaceae
- Growing form: Perennial herb. Rootstock erect, quite thin.
- Height: 10–30 cm (4–12 in.). Stem unbranched, densely haired, often purple at base.
- Flower: Perianth regular (actinomorphic), white, 4–7 cm (1.6–2.8 in.) wide. Like petals, glabrous, tepals 5, covering each other at base. Stamens many, yellow. Gynoecium with different leaves, pistils several. Flower usually solitary, long-stalked, flower-stalk densely haired.
- Leaves: Basal leaves 2–5 as a rosette, long-stalked, stalks densely haired, blade 3–5-lobed. Basal leaves overwintering. Stem leaves 3, short-stalked (1–3 cm (0.4–1.2 in.)), leaves whorled, blade 3-lobed, lobes toothed.
- Fruit: Elliptic, woolly-haired, short-tipped (0.5 mm (0.2 in.)), achenes (3–4 mm (0.12–0.16 in.)) forming a fairly erect infructescence.
- Habitat: Yards, parks, culturally-influenced land. Decorative plant and escape.
- Flowering time: May–June.
Snowdrop anemone is only found in Finland as an escape from yards and gardens. In the fruiting stage it can’t be confused with relatives because of its hairy achenes. (This helps wind-carried seeds travel further on the breeze.) In the flowering stage snowdrop anemone can be mixed with wood anemone (A. nemorosa) and three-leaved anemone (A. trifolia). Wood anenome is smaller, (almost) glabrous and its bottom leaves wither early. Three-leaved anenome’s leaflets are lobeless.
Anemonidium canadense (Anemone canadensis)
Culturally-influenced land in Finland is also home to another rare escape, Meadow anenome (Canada anemone, Round-headed anemone, Crowfoot). Like snowdrop anemone, meadow anenome is hairy, 1-flowered and large (up to 70 cm (30 in.) high). Its stem leaves are stalkless, which makes it easier to tell the two species apart. Both spread vegetatively by the root, and in good conditions they form dense stands and bloom early in the spring.
