Leek (Allium Porrum). Liliaceæ.
Seeds, sown very early in the spring, either out-doors or in a cold-frame.
Leianthus. Gentianeæ.
Seeds, under cover; or cuttings of young shoots may be made, and inserted in sandy soil under glass.
Leiophyllum (Sand Myrtle). Ericaceæ.
May be freely increased by seeds, sown in pans and placed in a frame. By layers in autumn.
Lemon (Citrus Limonum). Rutaceæ.
The named sorts are budded upon either orange or lemon stocks. Orange stocks are probably most generally preferred, as they are adapted to a great variety of soils, and vigorous trees nearly always result. The budding is performed in the same manner as upon the orange, which see. Lemons are often grown from cuttings of the mature wood, which are set in the open ground as soon as the spring becomes warm, or in a frame. Stocks for budding upon are sometimes grown from cuttings in this way.
Lentil (Ervum, various species). Leguminosæ.
Seeds, sown in early spring.
