Porcelain Garlic, Leningrad – 4 oz

Native to south-central Asia, garlic was probably domesticated from a single variety, Allium longicuspis, thousands of years ago. Today the plant is grown on every continent except Antarctica.

Garlic, which is a member of the same group of plants as the onion, has been cultivated for millennia. As a cultivated plant, it is so old that it is difficult to credit a country of origin for this vegetable. All modern garlic belongs to one of two subspecies: hardneck (ophioscorodon) or softneck (sativum). Hardneck subspecies try to produce flower stalks with small aerial cloves called bulbils. Hardnecks will not produce large bulbs underground unless the flower stalks are removed. There are three varieties of hardneck garlic: Purple Striped, Porcelain and Rocambole. Softnecks have lost the ability, for the most part, to produce a flower stalk. However, under certain climatic situations, the bulbs may try to produce a flower stalk known as bolting. There are three varieties of softneck garlic: Artichoke, Silverskin and Creole.

Porcelain Garlics are hardnecks. Most varieties have pure white skins and cloves so large that they are often mistaken for elephant garlic. The individual cloves are usually crystal white, hence the name Porcelain. One pound of bulbs averages 40 plants. Porcelain Garlics produce the tallest plants of all garlic cultivars. Some Porcelain plants can reach a height of 7 feet.

Each bulb contains 4-6 giant cloves with 4 cloves being the norm. The cloves are arranged in a single layer – no small interior cloves and the cloves are easy to peel. Unlike most hardnecks, Porcelains are fairly good storers.

The plants are very, very cold hardy, flourishing in Hardiness Zones1-4, but surprisingly the Porcelains also grow well in warmer climates. Porcelains, more than any other garlic cultivars, are extremely sensitive to spring growing conditions. This means that in the spring, to perform at their best, Porcelains need cool temperatures and abundant moisture. At harvest time, with most garlic, dry conditions help the garlic bulbs to finish well. With Porcelains, during harvest time it is recommended to expose the plants to moist conditions in order to help them to finish well.

Finally and perhaps most significantly, the Porcelains produce the highest yields of allicin, the sulfur compound which is most directly associated with garlic’s therapeutic benefits.

Leningrad, despite its name, is from Belarus. The very large bulbs produce 4 to 6 cloves whose flavor is typically Porcelain – slightly spicy and mild. Even for a Porcelain, Leningrad is extremely hardy and will not flourish in milder climates.

Garlic is best when planted in the fall, but can be planted in the spring as soon as the ground can be worked. If planting in the fall, plant 30 days before the ground freezes and mulch with straw or alfalfa hay if possible. Garlic must have some exposure to cold for several weeks or it will not bulb. Amend the soil with potash and phosphate before planting. Plant the cloves 1-2 in. deep and 4-6 in. apart in rows separated by 12-18 in.

Harvest in mid-summer when 2/3 of the stalk has turned brown or yellow. Dig the bulbs from the soil with stalks attached. Cure in a dry, shaded area with lots of air circulation for 4-6 weeks. Stalks can then be removed from the bulbs.
