Wild garlic and wild onion are similar perennial weeds. Tiny bulblets are formed underground. Soft bulblets germinate in the fall. Hard bulblets remain dormant over the winter, germinating the following spring or later. Wild garlic also reproduces by seed and by bulblets that it produces at the tips of some of its leaves. As the bulblets mature, they fall to the soil and sprout. Wild garlic spreads rapidly through the lawn and is very difficult to control. Its leaves are slender, hollow, and round. Greenish purple flowers bloom at the same height as the leaves.
Frequent mowing in the spring helps reduce vigor and spread.
