Geum aleppicum Jacq.
Yellow avens, common avens
Yellow avens is native to temperate regions of eastern Europe, Asia, and North America.
Plants: Plants are perennials, with stout, hairy stems, 12–39″ (30–100 cm) tall.
Leaves: Alternate, compound. Basal leaves are compound, while more upper leaves are variously shaped, roughly triangular or egg-shaped. Leaves are up to 4½ ⨉ 3½″ (11 ⨉ 8.9 cm), coarsely toothed, and hairy. Stipules, or tiny leaflets, are often visible at leaf axils.
Flowers: In groups of 1-5 at the end of branching stems. Flowers are ½–1″ (1.3–2.5 cm) around, with 5 yellow petals that are round to oval, and may have a dull point or notch at the tip. Between the petals are five sharp-tipped sepals in the shape of a star, though these fold back as the flower ages. The sepals are equal to or shorter than the petals in length. Many yellow-tipped stamens surround a greenish center of many carpels. Flowers appear from May-July.
Fruits: A velcro-like ball of tiny hooks, 1/16–⅛″ (2.5–5 mm).
Habitats: Forests, woodlands, swamps, fields, roadsides, trail edges, and stream banks, and prefers moist soil, such as meadows, open woods, thickets, and swamps.
