are borne on long stems in winter. The species is useful for growing 

 in a collection of plants in a warm greenhouse or conservatory. 

 The ordinary Coleuses are remarkable for the rich and varied colours 

 of their leaves, in which crimson and green, purple, yellow, and 

 white may be seen. Some have one-coloured leaves, others are flaked, 

 others marbled, others margined. Plants may be grown into a 

 nice size the same season if seed is sown in heat in early spring, and 

 with a little pinching they will be compact, shapely bushes. Special 

 varieties may be increased by cuttings. The weakest seedlings,

showing the most colour, are generally the best. Six-inch pots will 

 be large enough to flower them in, unless very large plants are 

 wanted, as they develop the richest colour when pot-bound. Very 

 few species are now grown. The following are good garden varieties : 

 Beckwith's Gem, Countess of Dudley, Decorator, Pineapple 

 Beauty, Pride of the Market, and Sunset. 



Colewort. See Kitchen Garden. 



Collinsia (collms-ia, after Mr. Collins. Ord. Scrophularineae) . 

 See Annuals. Coloured plates of the species will be found as follows : 

 bartsiaefolia in the Botanical Magazine, t. 3488 ; grandiflora in the 

 Botanical Register, t. 1 107 ; verna in the Botanical Magazine, t. 4927. 

 But bicolor is the most important. 



Collomia (collo-mia, from holla, glue, in allusion to the mucus on 

 the seed. Ord. Polemoniaceae) . Pretty hardy annuals (see Annuals 

 for culture), of which the most useful are coccinea, red; and grandi- 

 flora, red and yellow. Both grow about 2 ft. high and flower in 

 early summer. 



Coltsfoot, Tussilago. 



Columbine. See Aquilegia. 



Colutea, Bladder Senna (colu-tea, from koloutea, a name given by 

 Theophrastus. Ord- Leguminosae) . The most important species is 

 arborescens, a shrub growing some 10 ft. high, and producing yellow 

 flowers in summer, followed by inflated seed pods. It may be 

 raised from seed in spring and increased by cuttings in September. 

 No special soil is needed.
