A hardy bulbous perennial from South Europe, highly esteemed on the Continent for its white-skinned or rose-tinted bulbs, which are much used in soups, and in other ways. Garlic may be grown much in the same way as Shallots. The offsets or "cloves" from the older bulbs may be planted in February or early in March in rows about 1 ft. apart, and 6 in. asunder, and covered with about 2 in. of soil. When the leaves wither the bulbs are fit to lift and store away for use. In the most favoured parts Garlic may be planted in early autumn for earlier use the following year.
