Elephant garlic ( Allium ampeloprasum var. ampeloprasum) is a plant belonging to the onion genus. It has a tall, solid, flowering stalk and broad, flat leaves. The flavor is milder than garlic and can be eaten raw in salads, roasted, or sauteed, but is generally not a substitute for conventional garlic in cooking. It is sometimes confused with solo garlic.

The mature bulb is broken up into cloves that are large with papery skins, and these are used for both culinary purposes and propagation. Also, much smaller corms with a hard shell grow on the outside of the bulb. Many gardeners often ignore these, but if they are planted, they produce a nonflowering plant in their first year, which has a solid bulb, essentially a single large clove. In their second year, this single clove then, like a normal bulb, divides into many separate cloves. While it may take an extra year, it is desirable to plant these small bulbils (several can be produced by each bulb) and increase the harvest.

Unlike many garlics, elephant garlic does not have to be harvested or divided each year, but can be ignored and left in the ground without much risk of rotting. The plant, if left alone, will spread into a clump with many flowering heads (one stalk and flower from each clove, once the bulb divides). These are often left in flower gardens as an ornament and to discourage pests. Once they get overcrowded, the plant may not do as well, and growth is stunted, with some rotting. Elephant garlic is not generally propagated by seeds.

Like regular garlic, elephant garlic can be roasted whole on the grill or baked in the oven, then used as a spread with butter on toast. Fresh elephant garlic contains mostly moisture and foams up like boiling potatoes, whether on the stove or in a glass dish in the oven. Drying in the basement for a few months reduces the moisture content and brings out a fuller flavor.

Properties

When crushed and then analyzed using a DART ion source, elephant garlic has been shown to produce both allicin, found in garlic, and syn-propanethial-S-oxide (onion lachrymatory factor), found in onion and leek, but absent in garlic, consistent with the classification of elephant garlic as a closer relative of leek than of garlic. [1]

Cultivation

Elephant garlic can be planted at two different times of the year: spring and autumn. In warmer areas, it can be grown over winter for a late-spring harvest.

Allium ursinum, known as wild garlic, ramsons, cowleekes, cows's leek, cowleek, buckrams, broad-leaved garlic, wood garlic, bear leek, Eurasian wild garlic or bear's garlic, is a bulbous perennial flowering plant in the amaryllis family Amaryllidaceae. It is native to Europe and Asia, where it grows in moist woodland. It is a wild relative of onion and garlic, all belonging to the same genus, Allium. There are two recognized subspecies: A. ursinum subsp. ursinum and A. ursinum subsp. ucrainicum.

<i>Allium tricoccum</i> Species of wild onion

Allium tricoccum is a bulbous perennial flowering plant in the amaryllis family Amaryllidaceae. It is a North American species of wild onion or garlic widespread across eastern Canada and the eastern United States. Many of the common English names for this plant are also used for other Allium species, particularly the similar Allium ursinum, which is native to Europe and Asia. An edible plant, Allium tricoccum is used in a variety of North American and indigenous cuisines, and has also been used by Native Americans in traditional medicine.

<span class="mw-page-title-main">Tree onion</span> Species of flowering plant

The tree onion is a perennial plant similar to the common onion (A. cepa), but with a cluster of bulblets where a normal onion would have flowers. 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). However, some sources may still treat the tree onion as A. cepa var. proliferum or A. cepa Proliferum Group.

<span class="mw-page-title-main">White onion</span> Onion cultivar

White onion or Allium cepa are a cultivar of dry onion which have a distinct light and mild flavour profile. Much like red onions, they have a high sugar and low sulphur content, and thus have a relatively short shelf life. White onions are used in a variety of dishes, such as those of Mexican and European origin. Their uses in dishes often relate to their mild nature, they are often included in dishes to provide a light, fresh and sour taste to dishes and are often added uncooked to dishes such as salads.
