POINSETTIA . The Poinsettia pulcherrima of gardens (See also:

Euphorbia pulcherrima of botanists), a native of See also:Mexico and Central See also:America, with its brilliant See also:scarlet bracts, stands unrivalled amongst decorative See also:plants. The See also:white-bracted sort, See also:var. See also:alba, is not so effective, but the See also:double-flowered, var. plenissima, in which the brilliant inflorescence is branched, is as brilliant as the type, and keeps See also:long in See also:flower. They are increased by cuttings in See also:spring, which when taken off with a See also:heel strike freely in brisk See also:heat. They require See also:good turfy See also:loam, with an addition of one-See also:sixth of See also:leaf-See also:mould and a little See also:sand, and should be kept in a heat of from 65° to 70° at See also:night, with a rise of 10 by See also:day. To prevent their growing lanky, they should be kept with their heads almost touching the See also:glass; and as the pots get filled with roots they must be shifted into others, 7 or 8 in. in See also:diameter. About See also:August they may be inured to a heat of 50° at night, and should be brought to See also:bear See also:air night and day whilst the See also:weather is warm, or they may be placed out of doors for a See also:month under a See also:south See also:wall in the full See also:sun. This treatment matures and pre-pares them for flowering. In autumn they must be removed to a See also:house where the temperature is 50° at night, and by the end of See also:September some of them may be put in the See also:stove, where they will come into flower, the See also:remainder being placed under heat later for See also:succession. When in See also:bloom they may be kept at about 55° by night, and sb placed will last longer than if kept in a higher temperature.
