of easy culture in a compost of peat and loam, and may be 

 increased either by cuttings or by seeds. 



CALLISTEMON. [Myrtacese.] Beautiful evergreen 

 greenhouse shrubs, related to, and requiring the treatment of, 

 Melaleuca. The flowers are like bunches of coloured threads 

 set close together, so as to form the appearance of a bottle- 

 brush. C. lanceolatiis, flowers crimson. C. viridiflorus, 

 flowers green. 



CALLISTEPHUS. China Aster. [Composite.] The 

 China Aster, formerly called Aster Chinensis, and subsequently 

 CaUistemma hortense, is a favourite annual. The German 

 varieties, with flowers single, semi-double, or double, self- 

 coloured, red, pink, dark and light purple, or striped in all 

 ways, form a varied and striking feature towards the end of 

 the summer wherever they are introduced. To have them 

 in perfection, plant them in half well-decomposed dung and 

 half loam, or add plenty of manure to the soil of the garden. 

 Sow them in a hotbed in February or March ; plant them 

 out in May. If planted in beds — in which way they are 

 very eff"ective — let the bed be supplied with a good dressing 

 of dung, and plant them a foot apart every way ; keep them 

 clear of weeds, and in dry sultry weather let them have 

 plenty of water. They will bloom much finer treated in this 

 way, though, when planted about the borders wherever 

 there happens to be room, they add greatly to the beauty of 

 the garden, because their colours are so varied. The best 

 flowers should be marked for seeding. 



CALLUNA. Heather. [Ericaceae.] Pretty dwarf hardy 

 evergreen shrubs. Soil, peat. Increased by layers or by 

 seeds. 



CALOCHORTUS. [Liliaceee.] Very beautiful bulbous 

 plants, which appear to be difficult of cultivation. They seem 

 to do best when planted out in a frame into a bed of prepared 

 soil, consisting of sandy peat, with about a fourth part of loam 

 added. In this way they can readily be kept dry and cool in 

 winter during their resting season. Propagated by offsets. 



CALOPHACx\. [Leguminosse, § Papilionaceoe.] Hardy 

 deciduous shrub ; very ornamental when grafted half standard 

 high on Laburnum. Loamy soil. Propagated by seeds, or 

 cuttings, or grafts.
