THE NURSERY-LIST 283 



Cladrastis (Yellow-wood. Virgilia). Leguminosce. 



Multiplied by seeds in the open air in spring, or by cuttings of 

 the root, dug in fall and kept in sand or moss, moderately moist and 

 cool, until spring. 



Clarkia. Onagrcceoe. 



Raised readily from seeds sown in spring, either in the open or 

 started indoors. 



Clavija. Myrsinacece. 



Propagated by cuttings of half -ripened shoots. 



Clematis (Virgin's Bower). Ranunculacece. 



Seeds gathered as soon as ripe and stratified till spring usually 

 grow freely. Layers may be employed, put down preferably in 

 fall or spring. Some species, as C. recta, are increased by division. 



The kinds of clematis can be grown from cuttings of young 

 shoots, cut to single eyes and rooted in sand under glass in summer. 

 Cuttings of nearly ripe wood may also be similarly used in summer. 



The named varieties are grafted on pieces of roots of C. Flam- 

 mula or C. Viticella or others, the roots being taken from estab- 

 lished plants in the open. The cions are taken from house-grown 

 plants, and the grafts are handled in a cool greenhouse in summer 

 to fall or winter, whenever roots and good cions are available. 



Cleome (Spider Plant). Capparidaceoe. 



The commonly cultivated cleomes are annuals or treated as 

 such. Seeds may be sown under cover in spring and the plants 

 transferred to permanent quarters out of doors ; or the sowing may 

 be directly in the open. Cuttings of the perennial kinds may be 

 struck in heat. 



Clerodendron. Verbenacece. 



Raised from seeds and cuttings, usually started in small pots 

 in a soil of sand and peat (or leaf-mold). They should be started in 

 a rather close temperature of about 70. Cuttings are usually 

 taken from half-ripened wood. 



Clethra (White Alder). Clethraceos. 



Grown from seeds sown in spring in pans in sandy-peaty soil. 

 Propagated also by greenwood cuttings under glass ; by layers and 

 division of large plants.
