Appearance and Use:

This 20 inch tall plant is grown for its edible, enlarged, bulbous, underground portion which may be white, red, or yellow in color. The narrow foliage is light green and is very strong smelling. Harvest the bulbs when the leaves begin to fall over and the bulbs are easily pulled from the ground. If there is resistance, the roots are still actively growing and the onion should not be harvested. Hasten maturity by removing the tops and look to be able to harvest the bulbs in a week. Eat them fresh or dry them for storage
