Wild onions (Allium canadense) and wild garlic (Allium vineale) are both common wild plants belonging to the Allium genus, which encompasses various onion, garlic, and leek species. While they share similarities in appearance and habitat, there are distinct differences between the two that aid in their identification. Wild onions typically grow in clusters and have flat, solid leaves emerging from an underground bulb. The leaves are slender, often bluish-green, and can grow up to 20 inches tall.
