Green onions to the cook, scallions at the super market, Welsh onions in England, ciboule in France, or bunching onions in most books, they all refer to Allium fistulosum, a very distinctive member of the onion family. Bunching onions form perennial evergreen clumps up to 1 ft (0.3 m) in diameter and about 2 ft (0.6 m) tall. The leaves are hollow and tube-like, inflated their entire length. The bulbs are elongate and not much thicker than the stem. After a cold spell, bunching onions send up hollow stalks topped with little greenish flowers in round umbels (clusters with all the flower stems arising from the same point), that are 1-3 in (2.5-7.6 cm) in diameter. There are many cultivars, including some with red skins ('Santa Clause', 'Red Beard'); some with shorter, thicker stalks ('Shimonita'); some with larger bulbs ('Yoshima'); and some that are exceptionally cold-hardy, such as 'White Lisbon', 'Evergreen White Bunching' and 'Winter Over'. It is not unusual to harvest these under the snow. Bunching onions also have been hybridized with other Allium species, especially the common bulbing onion, A. cepa. These hybrids are sterile, and must be propagated by division of side shoots. 'Beltsville Bunching' is one such hybrid, noteworthy for its tolerance to hot and dry weather.

Culture
Usage
Spring onions are small and immature bulbing onions (Allium cepa, Cepa Group), and are used in place of bunching onions. The name, green onions, can refer to either bunching onions or immature bulbing onions. The term scallion is used for bunching onions and also sometimes for shallots (a.k.a. multiplier onions, A. cepa, Aggregatum Group), which are a type of bulbing onion grown for their small garlic-like brownish bulbs, as well as for their leaves which are similar to those of bunching onion. The common name, Welsh onion, is derived from the German, "Walsch", which means foreign, and has nothing at all to do with Wales. Some authorities place the onions, garlics, leeks and their relatives in a family of their own, the Alliaceae, and others put them in the lily family, the Liliaceae. There are about 400 species in the genus Allium, including some magnificent ornamentals. Steve Christman 2/1/00; updated 9/13/03
