Most epicureans use garlic on an almost daily basis to enhance the flavor of our culinary creations. Another plant that can be used to impart a similar, though lighter, flavor of garlic is the elephant garlic. How do you grow elephant garlic and what are some of elephant garlic uses? Read on to learn more.

What is Elephant Garlic?

Elephant garlic (Allium ampeloprasum) looks like a giant garlic clove but in fact, is not a true garlic; instead it is more closely related to a leek. It's a hardy bulb with large blue-green leaves. This perennial herb boasts an outsized pink or purple flower stalk that appears in the spring or summer. Under the ground, a large bulb consisting of five to six large cloves surrounded by smaller bulblets grows. This allium plant attains a height of about 3 feet (1 m.) from bulb to the tip of the strap-like leaves, and originates in Asia.

How to Grow Elephant Garlic

This herb is easy to grow and once established, requires little maintenance. Purchase large seed cloves from a supplier or try setting those found at the grocers. Elephant garlic bought at the grocers may not sprout, however, as they are often sprayed with a growth inhibitor to prevent sprouting. Look for heads that are firm with a dry, papery covering. With elephant garlic planting most any soil will do, but for the largest bulbs, begin with a well-draining soil medium. Dig down a foot (31 cm.) into the soil and amend with a 1.5 gallon (3.5 L.) bucket of sand, granite dust, humus/peat moss mix per 2 foot by 2 foot (61 x 61 cm.) to 3 foot by 3 foot (1 x 1 m.) sections and mix in well. Top dress with some well-aged manure and mulch around the plants with chopped leaves and/or sawdust to keep weeds at bay. This will also nourish the plants as the amendments decompose or break down. Elephant garlic prefers full sun and can be grown in temperate regions all the way into tropical zones. In cooler climates, plant in the fall or spring while in warmer regions the herb can be planted in spring, fall, or winter. Break up the bulb into cloves for propagation. Some cloves are much smaller and are called corms, which grow on the outside of the bulb. If you plant these corms, they will produce a non-blooming plant in the first year with a solid bulb or single large clove. In the second year, the clove will begin to separate into multiple cloves, so don't ignore the corms. It may take two years, but eventually you will get a good head of elephant garlic.

Caring for and Harvesting Elephant Garlic

Once planted, elephant garlic care is pretty simple. The plant does not have to be divided or harvested each year, but rather can be left alone where it will spread into a clump of multiple flowering heads. These clumps can be left as ornamentals and as deterrents to pests such as aphids, but will eventually become overcrowded, resulting in stunted growth. Water the elephant garlic when first planted and regularly in the spring with 1 inch (2.5 cm.) of water per week. Water the plants in the morning so the soil dries by nightfall to discourage diseases. Stop watering when the garlic's leaves start drying out, which is an indication it's harvest time. Elephant garlic should be ready to pick when the leaves are bent over and dying back -- about 90 days after planting. When half of the leaves have died back, loosen the soil around the bulb with a trowel. You can also top off the immature plant tops (scapes) when they are tender prior to blooming. This will direct more of the plant's energy into creating large bulbs.

Elephant Garlic Uses

Scapes can be pickled, fermented, stir fried, etc. and even frozen in a resealable bag, raw, for up to a year. The bulb itself can be used just as regular garlic, albeit with a milder flavor. The entire bulb can be roasted whole and used as a spread on bread. It can be sautéed, sliced, eaten raw, or minced. Drying the bulb out in a cool, dry basement for a few months will extend the life of the garlic and induce a fuller flavor. Hang the bulbs to dry and store for up to ten months.
