the Tuberose; a genus of plants belonging to the hexandria clas; and in the natural method ranking under the 10th order, Coronaria. See Botany Index. The varieties are the common tuberose, with single flowers,—double-flowered,—dwarf-stalked,—variegated leaved. They all flower here in June, July, and August.

All the varieties being exotics from warm countries, although they are made to flower in great perfection in our gardens by assistance of hot-beds, they will not prosper in the open ground, and do not increase freely in England; so that a supply of the roots is imported hither annually from Genoa, and other parts of Italy, by most of the eminent nurseries and seedsmen, and the Italian warehouse-keepers; generally arriving in February or March, time enough for the ensuing summer's bloom; and are sold commonly at the rate of twelve or fifteen shillings per hundred, being careful always to procure as large roots as possible, for on this depends the success of having a complete blow. Requiring artificial heat to blow them in this country, they are planted in pots, and plunged in a hot-bed, under a deep frame furnished with glass lights; or placed in a hot-house, where they may be blowed to great perfection with little trouble. The principal season for planting them is March and April; observing, however, that in order to continue a long succession of the bloom, it is proper to make two or three different plantings, at about a month interval; one in March, another in April, and a third the beginning of May, whereby the blow may be continued... Pollanthes continued from June until September; observing, as above mentioned, they may be flowered either by aid of a common dung or bark hot-bed, or in a hot-house.

With respect to the propagation of these plants, it is principally by offsets of the roots. The blowing roots that are brought annually from abroad for sale are often furnished with offsets, which ought to be separated previous to planting. Those also that are planted here in our gardens frequently furnish offsets fit for separation in autumn when the leaves decay: they must then be preserved in sand all winter in a dry sheltered place; and in the beginning of March, plant them either in a bed of light dry earth in the full ground; or, to forward them as much as possible, allow them a moderate hot-bed; and in either method indulge them with a shelter in cold weather, either of a frame and lights, or arched with hoops and occasionally matted; but let them enjoy the full air in all mild weather, giving also plenty of water in dry weather during the season of their growth in spring and summer. Thus let them grow till their leaves again decay in autumn: then take them up, clean them from earth, and lay them in sand till spring; at which time such roots as are large enough to blow may be planted and managed as already directed, and the small roots planted again in a nursery-bed, to have another year's growth; afterwards plant them for flowering. The Egyptians put the flowers of tuberose into sweet oil; and by this means give it a most excellent flavour, scarce inferior to oil of jasmine.
