Distribution | ||
Discussion | Road ditches, lawns, and other disturbed moist sites. Flowering Apr–Jul. 400–2800 m. BR, BW, Col, ECas, Lava, Owy. CA; Europe. Exotic. Allium triquetrum is cultivated for its attractive flowers. It readily escapes in south coastal Oregon and California and has potential to become invasive. |
Roadsides and other disturbed areas. Flowering Apr–Jul. 0–50 m. Est. Occasionally escaped in North America; North Africa, Asia, Europe. Exotic. This species may be conspecific with the cultivated leek A. porrum. |
