The Welsh Onion, also known as Allium fistulosum, is a perennial plant native to Asia. It has thin, hollow green leaves that grow from the base of the plant, and small white or pinkish flowers that bloom in the summer. The plant can grow up to about one foot tall and spreads through underground bulbs, forming clumps.
In terms of growing conditions, Welsh Onions prefer well-drained soil and full sun to partial shade. They are relatively easy to grow and can be cultivated in a range of climates, including cold and temperate regions. To successfully grow Welsh Onions, gardeners should plant the bulbs in the fall and water regularly.
Welsh Onions are winter hardy and can withstand frost. The leaves and bulbs of the plant are edible and can be used in a variety of dishes, including soups and salads. They can also be stored for later use by drying or freezing.
In addition to their culinary uses, Welsh Onions have a number of other uses. The leaves can be used as a natural insect repellent, and the plant is said to have medicinal properties. It is also valued by gardeners for its ability to attract pollinators and other beneficial insects.
Start seeds indoors in mid-late winter and transplant early spring. Start in mid-summer for overwintering onions, and transplant by end of summer.
