Blue plumbago (Plumbago auriculata) is a graceful, evergreen-to-semi-evergreen flowering shrub native to South Africa, prized for its clusters of delicate sky-blue flowers that can bloom much of the year in warm climates. It has a loose, sprawling growth habit and can be trained as a shrub, groundcover, or climbing plant, making it a popular choice for sunny California gardens. Blue plumbago prefers well-drained soil, regular water while establishing, and plenty of sunlight, and it can become quite vigorous when conditions are favorable.
