THE NURSERY-LIST 343 



Kalanchoe. Crassulaceo^ 



Propagated by seed when obtainable, but cuttings are more used. 

 They grow readily from several parts, as do the crassulas. 



Kale (Brassica oleracea var. acephala). Cruciferce. 



Increased by seeds, sown in the open in early spring in the North, 

 or in the fall in the South. They are hardy plants, standing much 

 frost ; should be grown in the cool season. 



Kalmia (Mountain Laurel. Calico Bush). Ericaceae. 



Kalmias may be increased by seeds, which should be sown in 

 spring in shallow pans of sandy peat or sphagnum, and kept in a 

 coldframe until the seedlings are large enough to transplant. After 

 being established, the young plants are hardened off and the next 

 year transferred to frames or open beds. By cuttings of young 

 shoots in sandy peat, placed in a shady situation under a hand- 

 glass (with much difficulty). Also propagated by layers. Usually 

 obtained from the woods. Varieties are veneer-grafted under 

 glass, on unnamed stocks. 



Kaulfussia : Charieis. 



Kennedya. Leguminosoe. 



Handled freely from seeds sown in spring or summer in pans or 

 flats ; also by cuttings of the firm green wood. 



Kentia : Howea. 



Kerria. Rosacece. 



Propagated by seeds when these are produced, as on the single- 

 flowered forms ; also by division, layers, and by cuttings of young 

 shoots under glass, and by ripened cuttings. In this country, 

 oftener increased by ripe-wood cuttings in fall. 



Kniphofia (Tritoma. Poker Plant). Liliaceas. 



Increased by seeds when they are produced, and by division of 

 the crown in early spring ; also by the offsets borne by some of the 

 kinds. Seeds of the common kinds should produce blooming 

 plants the second season, sometimes the first season. 



Kochia (Summer Cypress). Chenopodiacece. 



Grown from seeds which may be sown indoors in April and the 

 plants set out in May ; or sown in the open when the weather is 

 warm.
