Calendula (Pot Marigold). Composite. 



The common pot marigold (C. officinalis) grows quickly from 

 early-sown seeds where the plants are to stand ; or the seeds may 

 be started indoors and the plants transplanted for early bloom. 

 The plants of this genus may also be grown from cuttings. 



Call a of florists : Zantedeschia. 



Calliandra. Leguminosce. 



Cuttings in sand over bottom heat are used for propagation. 



Callicarpa (French Mulberry). Verbcnaccce. 



Increased by seeds, divisions, and by cuttings of the young 

 shoots in spring or summer under glass ; also by hardwood cuttings 

 and layers. 



Calliopsis: Coreopsis. 



Calliphruria. Amaryllidacece. 

 Propagated by offsets from the bulb. 



Callirhoe (Poppy-Mallow). Malvaceae. 



Perennials are propagated by seeds, division of roots, and 

 cuttings ; the annuals are easily raised from seeds. 



Callistemon. Myrtaceos. 



Multiplied by seeds, and by ripened cuttings (or wood firm at the 

 base) in sand under glass. Seeds should be sown in early spring 

 in finely sifted mixture of sand, leaf-mold and loam and covered 

 lightly, and placed in a cool greenhouse. The seed is gathered 

 in summer, the capsules being allowed to open naturally in a box 

 or on sheets of paper. 



Callistephus (China Aster). Composite. 



Quickly grown from seeds. For the main or late crop, seeds 

 may be sown in a seed-bed in the open or even where the plants 

 are to stand. For earlier bloom, seeds may be started indoors in 

 late spring. 



Callitris, Frenela. Pinaceoe. 



Multiplied by seeds when obtainable; and by cuttings under 

 glass in autumn, and wintered in a pit. 



Calluna (Heather). Ericaceae. 

 Propagated by cuttings of the tender shoots in sand under glass
