Koelreuteria. Sapindaceoe. 



Grown from seeds, stratified or sown in autumn ; also by root- 

 cuttings and young or low plants by layers. 



Kohlrabi (Brassica oleracea var. Caulo-Rapa). Cruciferoe. 



Propagated by seed sown in the open in early spring, or started 

 in a hotbed and the plants transplanted. Usually sown directly 

 in the open after the manner of turnips or rutabagas. 



Kumquat (Fortunella species). Rutaceos. 



Worked on stocks of three-leaved orange (Poncirus trifoliata), 

 rough lemon and sweet orange by the ordinary method of shield- 

 budding. See Orange. 



Laburnum (Golden-Chain). Leguminosce. 



The laburnums are increased by seeds sown usually in spring. 

 Layers and suckers are often used. The varieties are grafted or 

 budded on seedlings of the common sorts. See Cytisus. 



Lachenalia. Liliaceoe. 



Seeds usually start readily and blooming plants may be had the 

 same season if kept growing. Offsets from the bulbs are also used, 

 sometimes making blooming bulbs in one season. 



Lactuca. Composites. 



The ornamental kinds are grown readily from seeds. See Lettuce. 



Laelia. Orchidaceoe. 



Increased by pseudobulbs, as in cattleya. See also Orchids. 



Lagenaria (Gourd). Cucurbitacece. 



Propagated by seeds ; in the North these may be started indoors 

 in pots, but usually they are planted where they are to grow. 



Lagerstrcemia (Crape Myrtle). Lythracea. 



Propagated by seeds sown in boxes in autumn, and by layers and 

 cuttings of ripe wood. In long-season climates the plant may 

 bloom the first year from seed.

Increased by seeds, sown in fall and plants set out in spring, or 

 by seeds started in spring.
