- Description
-
Wild Onion is a bulbous perennial that is native to North Carolina and much of the United States. Wild Onions form grass-like clumps of leaves topped with rounded clusters of star-shaped pink or white flowers that bloom from late spring into summer. The plant produces a strong, onion-like odor when leaves are crushed or mowed. Wild onion is weedy in disturbed areas and can be found in meadows, thickets, fields, forests, and lawns.
Wild Onion grows about 18 in. tall and can spread quite freely when well sited. Both leaves and flowers have a delicious mild flavor while the bulb is crisp and mild with a pleasant flavor that is a leek or garlic substitute, according to taste. The plant spreads by bulb offsets and aerial bulblets.
Even though the plant is edible, there are better and less weedy plants to grow in the vegetable garden. Do not harvest plants in areas that herbicides have been used.
Insects, Diseases, and Other Plant Problems: Generally free of pests and disease. It is considered a noxious weed in several states.
