Onion seeds are cultivated in the spring and the resultant bulbs are harvested in autumn. These bulbs are similar in appearance to the mature onion, but much smaller in size. The starter bulbs are stored in a cool, dark place over winter. The next spring, the starter bulbs are planted in rows, 8 to 10 cm (3 to 4 in) apart. [1] Although this ...

The bulbs and bulblets of the twincrest onion may be planted as well. Maturity and flowering may come quicker planting by bulbs than planting by seeds. To do so, bulbs must be picked from the mature wild onion plant. These bulbs must then be stored in a dry environment (paper bags with dry peat moss is ideal).

[2] According the French ethnobotanist Michel Chauvet, the potato onion, also called family onion, forms several more or less flattened bulbs which, unlike shallots, remain enveloped in ...
Tree onions are also known as topsetting onions, walking onions, or Egyptian onions. Genomic evidence has conclusively shown that they are a diploid hybrid of the shallot and the Welsh onion (A. fistulosum). [2] [3] [4] However, some sources may still treat the tree onion as A. cepa var. proliferum or A. cepa Proliferum Group.
