Description
Blue Plumbago (Plumbago auriculata), also known as Cape Leadwort, is a lush, flowering shrub admired for its clusters of delicate, sky-blue flowers and graceful, arching stems. Native to South Africa, this plant blooms almost continuously from spring through fall, with flower clusters that resemble phlox. The blossoms create a soft, billowy display that attracts butterflies, adding a light and airy touch to gardens.
Blue Plumbago can grow up to 6-10 feet tall and wide, making it ideal for informal hedges, trellises, or as a sprawling ground cover. It thrives in full sun to partial shade and performs best in USDA zones 8-11, where it can be evergreen. In cooler climates, it is often grown as an annual or can be brought indoors to overwinter. Blue Plumbago prefers well-draining soil and is both heat- and drought-tolerant once established, making it a popular choice for low-maintenance, water-wise gardens.
Due to its sprawling nature, Blue Plumbago can benefit from light pruning to control its shape and encourage bushier growth. It pairs well with other sun-loving perennials and is perfect for borders, slopes, or cascading over walls. With its soft, blue flowers and resilient nature, Blue Plumbago brings a tropical, cottage-garden feel to landscapes and is a favorite for adding a splash of color and elegance.
