Genus of about 15 species of annuals, perennials, and evergreen shrubs and scandent climbers from tropical woodland and scrub in warm-temperate to tropical regions worldwide. An evergreen shrub with vine-like stems that form a rounded mound to about 5' high by 6'-8' wide. If desired, plumbago can be grown like a vine and allowed to scramble over adjacent supports. The blue flowers are about an inch in diameter and are arranged in clusters that resemble phlox. A white flowered form of this plant is available (P. auriculata alba). The 2" oblong leaves are a fresh, light green color. Keep it cool throughout the winter and early spring.
