THE NURSERY-LIST 293 



Crocus. Iridaceoe. 



Multiplied by the offsets or new corras that form on top or on 

 the side of the old corm. These are handled as are the cormels of 

 gladiolus and similar things, making blooming plants in one or 

 two years. Propagation is often effected by seeds, which are 

 likely to be overlooked because they form near the surface of the 

 ground. The seeds are sown in pots or boxes and exposed to 

 freezing before germination. Blooming plants should be had in 

 three years. 



Crotalaria (Rattle-Box). Leguminosoe. 



Multiplied by seeds sown early indoors, after being soaked in 

 warm water; the shrubby kinds by greenwood cuttings in sand 

 under glass. 



Croton: Codiceum. 



Crucian ella (Crosswort). Rubiacece. 



Handled mostly by division of the plants ; also by seeds and 

 sometimes by soft cuttings. 



Cryptanthus. Bromeliacecz. 



Propagation as for billbergia, which see. C. zonatm is the 

 common species, usually grown as tillandsia ; it makes parts that 

 may be used as offsets. 



Cryptomeria (Japan Cedar). Pinacece. 



Propagated by seeds ; also by cuttings of growing wood in sandy 

 soil under glass which often, as in the var. elegans, root freely. 

 The horticultural varieties are sometimes increased by grafting on 

 stocks of the species itself. 



Cucumber (Cucumis sativus). Cucurbitacece. 



Propagated by seeds. If sown outdoors, the operation should 

 be delayed until the weather is thoroughly settled. The early 

 outdoor crop is grown from seeds started indoors in pots or pint 

 berry-boxes, as the plants do not remove well if the roots are 

 disturbed. 



Cucumis: Cucumber, Gherkin, Melon. 

 Cucurbita : Gourd, Pumpkin, Squash. 

 Cucurbitacese. Cucurbits. 



The common method of propagating all species and varieties of 

 cucurbits is by seeds, which are large and usually germinate
