}}Achillea erba-rotta, common name simple leaved milfoil, is a perennial flowering plant of the genus Achillea, belonging to the sunflower family.[2] DescriptionAchillea erba-rotta is a polymorphic species, as its physical characteristics clearly vary depending on the variety. The biological form is chamaephyte suffruticose,[3] 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 {{convert|12|-|18|cm}} in height.[3] 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.[3] Cauline leaves are alternate, sessile, toothed and progressively linear, about 2–3 mm wide and 11–22 mm long.[3] Flowers are hermaphroditic and pentamerous, arranged in corymbs with many heads, about 3 mm in diameter, with rounded ligules.[3] The flowering period extends from July through August. The fruit is a flattened achene without pappus. DistributionThis typical plant of Alps is present in Italy, France, Switzerland and Austria.[3][4] HabitatIt prefers a sunny location in alpine pastures and rocky areas, at an altitude of {{convert|2000|-|2800|m}} above sea level.[3] Subspecies
