About Plumbago capensis  (Blue Plumbago)

This robust, evergreen shrub is known as Plumbago capensis. Commonly known as Blue Plumbago, this South African native shrub offers a cottage or tropical-like style inviting butterflies and other local pollinators. Its long arching branches are topped with 2″ long green leaves that darken with age. Clusters of five petaled, blue flowers cover this shrub with a repeat blooming lasting from the spring through fall seasons. Following its blooming period, fruit begin to emerge with sticky hairs that are known to litter the ground of the immediate area. Its upright growth habit helps it climb most vertical surfaces and can reach an average mature landscape size of 6-8′ by 8-12′. As a fast-grower, you can expect this variety to reach its average mature landscape size within 6-12 months.

Planting and care instructions

Plant Plumbago capensis in an area that receives full to partial shade using well-draining soil. Water regularly after planting to ensure that a healthy root system grows. After its first planting season you can reduce watering frequency to weekly except during periods of extreme heat. If desired, prune back growth before new blooms arrive in the spring.

Landscape design ideas

Blue Plumbago is an optimal choice to combat erosion. Plant on a hillside with 3-5′ between each plant to let it comfortably spread and fill out the area.  This shrub is a practical option for covering an unsightly fence or it can be used in place of a vine to cover a trellised patio or gazebo.
