Mouse garlic

Allium angulosum, commonly known as mouse garlic or angled onion, is a bulbous perennial herb in the family Amaryllidaceae native to temperate Eurasia, extending from central and eastern Europe across Russia and Siberia to northern China, where it grows in moist meadows, river banks, and damp grasslands. The plant develops from slender, cylindrical bulbs 1 to 2 centimetres long that are clustered on a short, oblique rhizome and clothed in brown fibrous tunics. Flowering stems are erect, 20 to 50 centimetres tall, and notably triangular or sharply angled in cross-section, distinguishing the species from related onions. The leaves are basal, linear, flat or keeled, 15 to 30 centimetres long and 2 to 5 millimetres wide, slightly fleshy and bright green. The inflorescence is a dense terminal hemispherical umbel 2 to 4 centimetres across bearing 30 or more star-shaped, pinkish-purple to rose-lilac flowers with prominent stamens, blooming in mid to late summer. Fruits are small three-celled capsules.
