Achillea millefolium ‘Summer Berries’ (Yarrow)

This cultivar of common yarrow occurs in pink, orange and red. This is either a cultivar of Achillea millefolium, or a cross between A. millefolium and A. ‘Taygetea’.

Leaves: Feathery, fernlike, bi- and tripinnately divided, attached almost directly to the stem in a spiral pattern. Individual leaves are 1¾–8″ (5–20 cm) long. The leaves are the most obvious identifying characteristic.

Flowers: Flowers are pink, orange, or red flat-topped or umbrella-shaped corymbs 3–4″ (7.6–10 cm) across. Each flower is a composite flower, about ¼″ (6.3 mm) in diameter, with three to eight ray petals and 10-40 disc flowers. Yarrows bloom from March to October.

Fruits: This variety does not spread on its own, so you will probably see it only in gardens.
