Description

Achillea erba-rotta is a polymorphic species, as its physical characteristics clearly vary depending on the variety. The biological form is chamaephyte suffruticose, as these plants have perennating buds borne close to the ground and are woody in the lower part of the stem, with herbaceous yearly branches. The primary root is a rhizome.

This plant reaches on average 12–18 centimetres (4.7–7.1 in) in height. The stems are woody and creeping, almost glabrous or with short hair and with erect flowering branches. Leaves of sterile branches are lanceolate-spatulate, 5-7 mm wide and 26-30 mm long, with 4-7 teeth on each side. Cauline leaves are alternate, sessile, toothed and progressively linear, about 2-3 mm wide and 11-22 mm long. Flowers are hermaphroditic and pentamerous, arranged in corymbs with many heads, about 3 mm in diameter, with rounded ligules. The flowering period extends from July through August. The fruit is a flattened achene without pappus.

Distribution

This typical plant of Alps is present in Italy, France, Switzerland and Austria.

Habitat

It prefers a sunny location in alpine pastures and rocky areas, at an altitude of 2,000–2,800 metres (6,600–9,200 ft) above sea level.
