Yellow or brown onions are sweet, with many cultivars bred specifically to accentuate this sweetness, such as Vidalia, Walla Walla, Cévennes, and Bermuda. [22] Yellow onions turn a rich, dark brown when caramelised and are used to add a sweet flavour to various dishes, such as French onion soup. Onions may be grown from seeds or from partially grown bulbs called "sets" or starter bulbs. Because onion seeds are short-lived, fresh seeds germinate more effectively when sown in shallow rows, or "drills," with each drill 12" to 18" apart. [57] [59] In suitable climates, certain cultivars can be sown in late summer and autumn to overwinter in the ground and produce early crops the following year. [14] Spring onions or salad onions may be grown from the Welsh onion ( A. fistulosum), as well as from A. cepa. Young plants of A. fistulosum and A. cepa look very similar, but may be distinguished by their leaves, which are circular in cross-section in A. fistulosum rather than flattened on one side.

After the 16th century, the helmet was long known only from the closely similar prints by Agostino Veneziano and others (it is not entirely clear which of these first created the image). These appear to combine the features of Süleyman lifted from other portraits available in Venice, while the helmet itself was recorded when it was exhibited in Venice, before it reached the sultan. The helmet was widely thought to be a fanciful invention of the printmakers, until 20th-century scholars rediscovered the records of the real object.

Imperial Library Pliny the Elder of the first century AD wrote about the use of onions and cabbage in Pompeii. He documented Roman beliefs about the onion's ability to improve ocular ailments, aid in sleep, and heal everything from oral sores and toothaches to dog bites, lumbago, and even dysentery. Archaeologists unearthing Pompeii long after its 79 AD volcanic burial have found gardens resembling those in Pliny's detailed narratives. [18] According to texts collected in the fifth/sixth century AD under the authorial aegis of "Apicius" (said to have been a gourmet), onions were used in many Roman recipes.

Caution advised!Onions have particularly large cells that are readily observed under low magnification. Forming a single layer of cells, the bulb epidermis is easy to separate for educational, experimental, and breeding purposes. [31] [32] Onions are therefore commonly used in science education to teach the use of a microscope for observing cell structure. [33] Dye Brewster, James L. (1994).
