Onion, Chives, Garlic, Scallion, Leek or Ornamental Onion

This is a large and very diverse genus of monocotyledonous plants. Depending on the taxonomic source, there are somewhere between 260 and 979 species of Allium. Almost all of them occur in temperate regions of the Northern Hemisphere with a small number also from tropical regions. The genus name is from the Latin word for garlic. Originally thought to possess medicinal and aphrodisiac properties in addition to flavoring.

Alliums come in a wide variety of sizes and colors from yellow to white to purple. Although several form a globe type bloom others have a more open flower. This genus includes edible plants such as onions, chivers and garlic.
