winter water must be given with great care, the roots being kept rather dry; in summer, when the plants are growing freely, water must be supplied in plenty. The best of the pleromas for the warm greenhouse is P. sarmentosa, which makes a nice specimen plant in a pot if trained to a wire balloon. The flowers are of a fine violet colour, shading into blue.

Plumbago.—The fast growing blue-flowered P. capensis is a good pillar plant and will supply useful flowers for bouquets. Cuttings of young wood strike as freely as fuchsias. When growing freely it should be frequently syringed.
