THE NURSERY-LIST 345 



Lamarckia. Graminece. 



Propagated by seeds, sown in spring or fall, and the plants set 

 out in the spring ; also by spring-sown seeds. 



Lantana. Verbenacea:. 



Increased by seeds, which give new varieties, and by cuttings, in 

 fall or spring, from good growing wood, in sand in a warm house or 

 frame. For florist's use, old plants are lifted or repotted in early 

 autumn to stimulate cutting wood; cuttings are then taken in 

 winter or spring and blooming plants are had for summer. 



Lapageria. Liliacece. 



Seeds may be sown as soon as ripe, when procurable, in a sandy 

 peat soil, and kept in a moderate heat. Increased by layers of 

 firm strong shoots from which some of the leaves have fallen. The 

 shoot may be bent back and forth in a box of sand and peat, being 

 pegged down and then covered with the earth ; keep moist, and 

 shoots will start from the joints and when rooted may be separated 

 and potted. 



Lapeyrousia. Iridacece. 



Increased by division of the bulbs. 



Larix (Larch. Tamarack). Pinacea. 



Usually grown from seeds, which should be kept dry over 

 winter and planted early in spring; shade the young plants. 

 Varieties, as the weeping sorts, are worked on common stocks 

 (usually the European larch). The grafting may be done by the 

 whip method, outdoors early in spring. Rare sorts are sometimes 

 veneer-grafted under glass. Rarely increased by cuttings of 

 nearly ripened wood under glass or by layers. 



Lasiandra : Tibouchina. 



Latania. Palmacecs. 



Propagated by imported seeds sown in strong bottom heat. See 

 Palms, page 377. 



Lathyrus (Vetchling). Leguminosce. 



Propagated by seeds, sown very early in the open ; the perennials 

 also by seeds, something by division, and special varieties by cut- 

 tings in the fall, after the flowering season, or in spring from old 

 plants stored in the greenhouse. The sweet pea may be sown before 

 frosty weather is passed, and south of Norfolk it is usually satis-
