Cineraria (Senecio cruentus). Composites . 



Raised from seeds, usually from well-grown commercial seed. 

 The florist's cineraria is usually a winter and spring bloomer. 

 Two batches of seedlings are usually raised for succession, one 

 from seed sown in August and another in September or early 

 October. If bloom is wanted for early winter or late autumn, 

 seed should be sown in May. Seed is sown in pans, flats or pots 

 on the surface of finely prepared and leveled soil and covered with 

 sifted sand. Water with care, keep uniformly moist, protect 

 from drafts and direct sun, and prick out as soon as large enough 

 to handle. Keep them shifted as needed, not in too large pots at 

 each shift, and growing without check ; do not allow them to bloom 

 prematurely. 



Cinnamomum. Lauracece. 



Increased by cuttings and seeds. The seeds should be sown as 

 soon as ripe in a shaded bed, the seedlings being transplanted when 

 very small into pots and kept until set out permanently. Cuttings 

 of half-ripened wood may be rooted in the spring in moderate 

 heat, in coarse sand. In this genus are included cinnamon, 

 camphor and cassia-bark. 



Cissus. Vitacece. 



Grown from seeds, when obtainable ; also by cuttings of green 

 or mature wood. Handled essentially as for the grape, ampelopsis 

 and parthenocissus. 



Cistus (Rock Rose). Cistaceoe. 



Seeds sown in flats or pans in spring, protected from sun, give 

 good results ; by layers ; by cuttings under glass in peaty soil in 

 late spring or summer. 



Citron (Citrus Medico). Rutacece. 



Propagated from seeds ; by mature cuttings, the same as the 

 lemon; and more commonly by budding on sour orange, sweet 

 orange or lemon stocks. See under Orange. 



Citrullus : Watermelon. 



Citrus. Rutacece. 



Propagated by seeds, layers, cuttings, inarching, grafting and 

 budding. For particular methods, see Grapefruit, Kumquat, 

 Lemon, Lime, Orange.
