Blue Plumbago Overview

Plumbago auriculata is a popular, evergreen shrub that scrambles (with support) over walls and archways. It can also be trained against a sheltered, sunny wall outside - or under glass. Its beautiful light to medium blue flowers appear from summer to autumn and its evergreen leaves are spoon-shaped and light green. It is a vigorous plant that grows fast. Because it is tender, Cape leadwort - a name by which it's also known - is best grown as a conservatory plant in frost-prone areas. Preferring full sun outdoors, it can tolerate partial shade and needs fertile, well-drained soil. Originally from South Africa, Plumbago auriculata is popular with a wide range of wildlife. It is used as a traditional medicine and its sticky flowers are used by children to make earrings!

How to propagate Blue Plumbago


Cuttings can be used but are less successful when compared to suckering. Use semi-hardwood or hardwood cuttings and place in well-drained sand until roots have formed.


Sow in autumn, 3m apart and place a thin layer of soil over the seeds. Do not sow deep. Germination should be more or less one month.


The best way to propagate the Cape Leadwort is to remove the sucker - with roots and stem - and replant.
