=Lagetta= (Lace Bark). _Thymelæaceæ._ Usually increased by cuttings of firm shoots, placed in sand under glass, in bottom heat. =Lagunaria.= _Malvaceæ._ Seeds. Cuttings of half-ripened shoots, placed under glass, in a gentle heat. =Lambertia.= _Proteaceæ_. Increased by seeds, sown in slight heat. By cuttings, made of young and rather firm shoots. =Lantana.= _Verbenaceæ._ Seeds, which give new varieties. Cuttings, in fall or spring, from good growing wood, in sand in a warm house or frame. =Lapageria=, Capia, Phænocodon. _Liliaceæ._ Sow seeds when ripe in a sandy peat soil, and keep in a moderate heat. Increased by layers of firm, strong shoots. =Laportea.= _Urticaceæ._ Propagated by seeds, or by cuttings placed in sand, in heat. =Lardizibala.= _Berberideæ._ The cuttings, made of half-ripened shoots, should be inserted in sandy soil under glass. =Larix= (Larch, Tamarack). _Coniferæ._ Seeds should be kept dry over winter and planted early in spring. Shade the young plants. Varieties, as the weeping sorts, are worked upon common stocks. The grafting may be done by the whip method, out-doors early in spring. Rare sorts are sometimes veneer-grafted under glass. =Larkspur.= See Delphinium. =Lasiandra.= _Melastomaceæ._ Propagated by cuttings of the growing wood under glass. =Lasiopetalum.= _Sterculiaceæ._ Seeds. Make cuttings in spring of the half-ripened wood, and insert in sand, under glass. =Latania.= See Livistona. =Lathyrus= (Sweet Pea, Vetchling). _Leguminosæ._ Seeds, sown very early in the open. The perennials also by seeds, sometimes by division. =Lattice-leaf.= See Ouvirandra. =Latua.= _Solanaceæ._ Propagated by cuttings, placed in sand under glass. =Laurel, Mountain.= See Kalmia. =Laurus= (Laurel). _Laurineæ._ Increased by seeds, layers, and by cuttings, placed under a hand-glass in sandy soil. Also propagated by root-cuttings. =Laurustinus.= See Viburnum. =Lavandula= (Lavender). _Labiatæ._ Divisions. When the flowers are fully expanded, cuttings may be made. These should be inserted in sandy soil, under a frame. =Lawsonia=, Alcanna. _Lythrarieæ._ Increased by cuttings of ripened shoots, placed in sand under a glass, in heat. =Laxmannia.= _Liliaceæ._ Seeds. Propagation is usually effected by divisions or bulbels. =Layia.= _Compositæ._ Increased by seeds, sown in a hot-bed, or in the open border in the south. =Leaf-Beet= or =Chard=. See Beet. =Ledum= (Labrador Tea). _Ericaceæ._ Propagated by seeds and divisions, but principally by layers, in sandy peat soil. =Leek= (_Allium Porrum_). _Liliaceæ._ Seeds, sown very early in the spring, either out-doors or in a cold-frame. =Leianthus.= _Gentianeæ._
