factory if sown in the fall. See Sweet Pea. The everlasting pea 

 (L. latifolius) is increased by seeds, division and cuttings. 



Laurus (Laurel). Lauracece. 



Propagated by seeds, layers and by cuttings, under glass in 

 sandy soil ; also by root-cuttings. The bay tree (Laurw nobilis) is 

 grown from cuttings of well-ripened wood 3 to 4 inches long, struck 

 in sharp sand under glass, bottom heat not being essential ; the 

 rooted cuttings are potted off and grown under glass or in a hotbed. 



Lavandula (Lavender). Labiates. 



Cuttings may be made in late fall or early spring, of the season's 

 growth with a heel of older wood. These should be inserted in 

 sandy soil, under a frame. Also propagated by seeds and division ; 

 but seeds do not give desired varieties and plants from divisions 

 are more susceptible to disease. 



Lavatera. Malvaceae. 



Propagated by seeds. The perennial species can probably be 

 multiplied by cuttings. 



Layia. Composite?. 



Handled by seeds, sown in a hotbed, or in the open border in the 

 South and for late bloom. 



Ledum (Labrador Tea). Ericaceae. 



Multiplied by seeds sown in spring in peaty soil, much as azaleas ; 

 also by division and by layers. 



Leek (Allium Porrum). Liliaceoe. 



Propagated by seeds, sown very early in the spring, either out- 

 doors or in a coldframe ; usually started where the plants are to 

 stand ; frost-hardy. 



Leiophyllum (Sand Myrtle). Ericaceae. 



Increased freely by seeds in boxes or pans and placed in a frame ; 

 also by layers in autumn. 



Lemon (Citrus Limonia). Rutacece. (H. H. Hume.) 



The named varieties are propagated by budding on sour orange 

 or rough lemon stocks. Sour orange stocks are most commonly 

 used as they are adapted to a wide range of soil conditions. For 

 indoor culture Poncirus trifoliata stock is best. For methods of 

 propagation, see Orange. Lemons may be grown from mature
