jiS PLANT CULTURE 



Propagation. Effected by putting in cuttings of the ripe 

 growths out of doors in Autumn. Good-sized branches can be 

 layered successfully. 



JUNIPERUS (Juniper). J. sabina var. tamariscifolia is a 

 most useful dwarf, trailing evergreen, seldom growing over i8 inches 

 high. J. procumbens is another species of creeping habit. 



Propagation. Cuttings may be put in after the first sHght 

 frost. Where only a limited number of this and other evergreen 

 coniferous shrubs is required, the best method, is to fix up 

 a few boxes, say about 4 inches deep, with sandy potting soil at the 

 bottoms and pure sand on top; make the cuttings about 6 

 inches long, half of which should be in the soil. Put them in fairly 

 close together, and firm well. Give one good watering. Stand the 

 boxes in the coolest part of the house under the benches; keep moder- 

 ately damp, and by Spring, if the conditions have not been un- 

 favorable, a goodly percentage will have rooted. If not too close 

 together they will take little harm from passing the Summer in 

 the same boxes. The kinds available for this method of propagation 

 are Biotas, Cupressus, Thuja, Retinispora, Cephalotaxus and 

 Taxus. 



KALMIA (American Laurel). The Mountain Laurel, Kalmia 

 latijolia is a native evergreen shrub growing from Maine southward. 

 In the Northern States it is a bush, 4 to 8 feet high. Farther south 

 it is frequently met with 20 feet high. It blooms during May and 

 June. It is cultivated much in the same way as Rhododendrons; 

 but under cultivation we seldom see the plants flourishing equal to 

 those in their native habitats. K. polijolia {glauca) has lilac- 

 colored flowers, and whitish under the leaves; K. angiislifolia has 

 purple flowers. All three are used for forcing, imported plants being 

 employed for the purpose. A', angustifolia has lateral corymbs; 

 in K. latifolia and K. polifoUa they are terminal. Manure of any 

 kind should not be used in the cultivation of these plants. 



Propagation. Raised from seeds sown in peaty soil or from 

 half-ripe wood cuttings and layers. 



KERRIA (Corchorus). Kcrriajapouica is a popular flowering 

 shrub which is not too particular as to soil or situation. It attains a 

 height of about 6 feet. There are three forms — double, known as 

 the Globe-flower, and single flowered and variegated. They are 

 all good. The variegated one keeps the color in the leaves all 

 through the season just as showy as in Spring; it usually bears a 

 crop of flowers, which are bright yellow, over an inch in diameter,
