Tree onion
(Redirected from Allium × wakegi)
Tree Onion (Allium × proliferum), also known as Egyptian onion, top onion, walking onion, or catawissa onion, is a type of onion that produces a cluster of bulblets at the top of its stalk instead of seeds. These bulblets can be planted to produce new plants, making the tree onion a type of vegetatively propagating perennial.
Description[edit | edit source]
The tree onion plant is similar in appearance to the common onion (Allium cepa), but differs in its method of reproduction. Instead of producing seeds, the tree onion produces a cluster of small bulblets at the top of its stalk. These bulblets, which are essentially miniature onions, can fall to the ground and take root, producing new plants. This method of reproduction gives the tree onion its alternate names of "walking onion" and "Egyptian onion".
Cultivation[edit | edit source]
Tree onions are easy to cultivate and can be grown in a variety of soil types, although they prefer well-drained soil. They can be planted in both spring and autumn, and are generally harvested in late summer. The bulblets can be used in the same way as regular onions, and have a strong, pungent flavor.
History and Distribution[edit | edit source]
The exact origins of the tree onion are unknown, but it is believed to have been cultivated in the Middle East for thousands of years. It was introduced to Europe and North America by traders and explorers, and is now grown in many parts of the world.
Uses[edit | edit source]
In addition to their use as a food crop, tree onions are also grown for their ornamental value. The unusual appearance of the bulblet cluster at the top of the stalk makes them a unique addition to any garden.
