Achillea millefolium

Growing form

Perennial herb.

Size

30–60 cm high.

Stem

The stem is robust, erect, simple or branched at the upper part, pilose and weakly fragrant with herb-like aroma. The plant forms subterraneous runners.

Leaf

The leaf arrangement is spiral. The lower leaves are petiolate and the leaves higher up on the stem are apetiolate. The lamina is elongate, two or three times pinnatisect with typically over 15 pairs of lobes. The lobes are narrow, mostly similar to one another, and the terminal lobe is cuspidate. At least the abaxial side of the leaf is pubescent.

The capitulescence is dense and panicle-like. The capitula are 3–6 mm wide. The involucral bracts are arranged in multiple rows. The margin of the involucral bracts is greenish or brown. There are 3–5 ray florets, which are pistillate florets and whose corolla is ligulate and typically white, occasionally pink or purple. The disc-florets are bisexual with a tubular corolla.

Fruit and seed

The achene is not angular. Pappus is absent.
