The flowers are golden yellow, rather large, and borne 
in clusters in the axils of the leaves. It is admirably 
adapted for planting on dry, warm ledges in the rock 
garden, and produces a rich colour effect during April 
and May. C. kewense, a hybrid between the two fore- 
going species, and its decumbent habit renders it of 
special value for planting on banks and on broad ledges 
in the rock garden. The flowers are produced in April 
and May, and are large in size and of a pleasing shade 
of primrose yellow. C. pracox, a charming species of 
slender growth, and forming a dense bush. The flowers

large and of arich purple hue. C. purpureus albus, white ; 
and C. purpureus ratisbonensis, yellow, are desirable forms.

Andreanus, is the best for the garden. The flowers

or taking cuttings is early in the autumn, when the
