CRASPEDIA. 



Half-hardy anmrils (ord. Composite), of wliicli 

 seeds should be sown in boxes in March, the seed- 

 lings being duly thinned ami finally planted out of 

 doors in rich, well-drained toil at the end of May.

CRASSULA. 



Description. In the main this is a genus (urd. 

 Crassulaceae) of South African plants which thrive 

 best in the greenhouse. There are many scores of 

 species, including annuals and herbaceous and 

 shrubby perennials, but the number of those that 

 have horticultural value is very limited. As a rule, 

 they are grown for the beauty of their flowers, but 

 a few have dislinctiveness of leafage. 



Propagation. Increase is readily effected by 

 cuttings of the upper portions of the growth in 

 summer. Expose the selected portions to the sun 

 for a day or two, and then insert them thinly in 

 pots of loam, leaf mould, and sand. These will 

 form neat plants, and will, flower in the second 

 season from insertion. Five or six will form a 

 specimen in one large pot. The plants usually 

 flower in alternate seasons. 



Soil. Two parts fibrous loam and one part leaf 

 soil, with sharp sand and pounded bricks. 



Other Cultural Points. After potting, water 

 must be given with judgment, or disappointment 

 will ensue. After flowering, reduce the water 

 supply, and in a few days cut the growths back 

 to near the point of origin. A greenhouse is the 

 best place during winter. When growth recom- 

 mences repot, making the new soil lirrn about the 

 roots. If large specimens are required, t he growths 

 must bo judiciously pinched.

CRATVEGUS. (THOHN.-) 



Description. The Thorns (ord. Rosaces) are 

 without rivals amongst trees of comparatively 

 small stature for the embellishment of shrubberies 

 and other portions of the garden. The large 

 majority are white flowered, but they vary very 

 considerably in the form, colour, and size of the 

 fruit. 



Propagation. Seeds sometimes germinate 

 quickly, at other times taking from two to three- 

 years. Specially good varieties may be perpetuated 

 by budding or grafting upon the common White- 

 thorn. 



Soil. These trees have the great merit of flourish- 

 ing in any ordinary fertile garden soil or parkland. 



Other Cultural Points. All the species are 

 hardy. One or two, notably Pyracantha and its 

 varieties, display the remarkable beauty of their 

 berries in winter when grown upon a wall. Superb 

 specimens of Pyracantha Lalandi are frequently 

 seen upon walls. Pyracantha thrives in towns.
