ALLIUM (from all, meaning hot or burning; in allusion to the well-known properties of the Onion tribe). Including Porrum, Schœnoprasum. ORD. Liliaceæ. Hardy bulbous plants, with flat or terete radical leaves, and capitate or umbellate flowers, enclosed in a membranous spathe at the summit of a slender, naked, or leafy scape; perianth spreading or campanulate. They are of very easy culture, increasing rapidly by offsets. The little bulbs, which are produced in clusters, may be separated and replanted, in autumn or early spring, about 4in. deep. Seeds are also easily obtainable. These may be sown thinly in light soil, in February or March, where they should remain until the autumn or following spring, when they may be transplanted to their flowering situations. During the growing season, all the attention required will be to keep the plants free of weeds, and place stakes to the tall-growing kinds.
