Originating from South Africa
Evergreen shrub, usually grown as a climber with sky blue flowers in summer and autumn. Plumbago produces long, leggy shoots and these require tying to wires or a framework. This is worth the effort as few other plants produce such a profusion of intense sky blue, phlox-like flowers over such a long period of time, often right up to Christmas.
Although Plumbago has been known to survive outdoors in sheltered gardens in very mild winters it is considered a conservatory plant and is happy under glass in filtered light – direct sunlight may lead to leaf scorch. In unheated conservatories, the foliage may be severely damaged – chop it back, almost to ground level and it will rapidly re-shoot and flower the same season. Try growing in a hanging basket or wall mounted container and allow the stems and flowers to cascade.
Grow in loam-based compost in indirect light.
Height and spread after 1 – 2 years 2m x 1m
