Crambe (Flowering Seakale). — To this genus belongs 
the edible Seakale. The only species suitable for flower 
garden culture is C. cordifolia, a native of the Caucasus, and 
a hardy herbaceous perennial, growing upwards of 6ft. high. 
It is a very handsome plant, with large, heart-shaped leaves 
of an imposing aspect, and an immense head of white flowers 
borne in spreading panicles in summer. A fine plant for 
large, shady, herbaceous borders or as a solitary plant in the 
wild garden. Plant in ordinary soil in autumn. Increased by 
seeds sown outdoors in April, or division of the roots in 
autumn or March. Nat. Ord. Cruciferae. 
Crepis (Hawk’s-head). — Only one species of this genus 
of Composite plants is worth growing, and that is C. rubra. 
This is a European annual, growing 8 to ioin. high, and 
bearing red flowers in autumn. It is suitable for dryish, sunny 
borders where the soil is more or less sandy. Sow seeds in 
April where the plants are required to grow. 
Cyananthus. — Hardy alpine plants of procumbent 
habit, natives of the Himalayas, and members of the Cam- 
panula order (Campanulaceae). Two species are grown, 
namely, C. incana, growing 3 to 4in. high, and bearing azure 
flowers in August; and C. lobatus, of similar height, but 
bearing purplish-blue flowers in August. The former succeeds 
best on a sunny, well-drained rockery in sandy peat, and the 
latter in peat and leaf-mould in semi-shady clefts of the rocks 
or stones. This species likes a moist medium for its roots. 
Plant in autumn or spring. Increased by cuttings in sandy 
peat in a cold frame in summer. 
Dactylis (Cock’s-foot Grass). — C. glomerata, the Cock’s- 
foot Grass, is a native pasture grass of no value from a garden- 
ing point of view. A pretty silvery-striped form of it named 
variegata, is, however, largely grown as an edging plant for 
flower beds and borders. It is of dwarf, tufted habit, growing 
only a few inches high. It will succeed in any soil that is not 
too dry, and should be planted in autumn or spring a few 
inches apart. Easily increased by division of the plants in 
October. 
Da,rlf ngtonia. (Californian Pitcher-plant). — An inter- 
esting and curious plant from California, and a member of 
the Sarracenia order (Sarraceniacese). The only species is D. 
californica, and this produces tubular leaves 1 to 2ft. long, each 
furnished at the apex with a hood or sac ending in two lance- 
shaped lobes. The leaves are strongly veined and the hood 
has a crimson tint. Inside the tubular leaves are reflexed 
hairs, which prevent insects entering at the orifice of the
