in a cool house in autumn. Plants for propagating stock should 

 be potted in September and kept in a cold frame or pit till January ; 

 on being brought into a warm greenhouse, cuttings may be taken 

 in about two weeks and will root readily in sand. C. vulgaris is 

 propagated from cuttings or seeds ; its varieties by cuttings. 



Calochortus (Mariposa Lily). Liliaceoe. 



Propagated by seeds, offsets, and by the little bulblets on 

 the stem. Sow seeds as soon as ripe, or early the next year. As 

 they may have to remain in the pans or flats the second year, it is 

 well to sow the seed thinly. Keep in a frame or cool house. Pot 

 them off the third season ; that or the following season they should 

 bloom. Offsets are removed when the plants are shifted, or in a 

 dormant period. 



Calonyction (Moonflower). Convolvulacece. 



Raised from seeds, which may be cut or filed to hasten germina- 

 tion. For short-season climates, the plants should be started 

 indoors. Often retained in the genus Ipomcea. 



Caltha (Marsh Marigold. " Cowslip " in America). Ranunculacece. 

 Readily increased by division of the plants, or of the rhizomes 

 of some species. Fresh seeds sown in moist cool earth give satis- 

 factory results. 



Calycanthus (Sweet-scented Shrub. Carolina Allspice). Calycan- 



thaceoe. 



Propagated by seeds sown in spring in a frame ; by divisions or 

 suckers, and by layers in summer. 



Calystegia : Convolvulus. 



Camassia (Camass or Qua'mas). Liliaceae. 



Seeds grow readily, giving blooming plants in three or four years ; 

 also increased by offsets. 



Campanula (Bell-flower). Campanulacece. 



Increased by seeds started early under glass. Annuals may be 

 raised in the border by seeds sown late in April or May, or raised 

 in the greenhouse and transplanted. The perennials are also prop- 

 agated by dividing the roots, or by cuttings of shoots in spring. 

 The Canterbury bell (C. Medium) is biennial. Seeds sown in 

 late spring will give good bloom the following year. Plants for
