Bulbs
A Bulb is formed upon or beneath the ground, and is a swollen stock, consisting, in the first place, of a more or less fleshy disk, which below gives rise to the roots; secondly, of more or less fleshy coats, or scales, borne on the disk; thirdly, of a more or less central shoot, equally borne by the disk, protected by the coats or scales already mentioned, and formed of rudimentary leaves and flowers. In some instances, small Bulbs, called Cloves, are formed at the base of the scales of the original Bulb; these are destined to reproduce the plant. Shallot and Garlic are good examples. Bulbs are, in fact, storehouses, husbanding the strength and energy acquired by the plant during one season, for the exigencies of the next. They are classified under two sections-Scaly and Tunicated. In the former, the scales of the Bulb are imbricated, as in the Lily; in the latter, they form continuous coatings, one within the other, as in the Hyacinth, &c. In several Lilies, young Bulbs are found growing in the axils of the leaves, when they are known as Bulbils. Bulbs is also a popular term given to Dutch Flower Roots, mostly arriving here in the autumn for spring flowering. Crocus, Colchicum, Cyclamen, Gladiolus, and several others, are not Bulbs, but Corms. The flowering season varies according to the different sorts of Bulbs. The majority may be lifted and kept tolerably dry during the resting period; but they wither and become exhausted if not replanted at the proper time, thereby causing many failures. Dutch Bulbs generally arrive in September, and the best results are obtained from those potted or planted at once, although some for succession may be kept in reserve up till the beginning of November. The failure in cultivating imported Liliums and other Bulbs may be often caused by their long-continued confinement in a dry atmosphere, whereby their vitality is often almost lost. The roots of some Bulbs are nearly always, more or less, in action, and these, especially, should not be kept out of the ground for any length of time.
