Blue Cape Plumbago is a multi-stemmed evergreen shrub with a shapely form and gracefully arching branches. Its average texture blends into the landscape, but can be balanced by one or two finer or coarser trees or shrubs for an effective composition.
This is a relatively low maintenance shrub, and is best pruned in late winter once the threat of extreme cold has passed. It is a good choice for attracting butterflies to your yard. It has no significant negative characteristics.
Blue Cape Plumbago is recommended for the following landscape applications;
Planting & Growing
Blue Cape Plumbago will grow to be about 3 feet tall at maturity, with a spread of 4 feet. When grown in masses or used as a bedding plant, individual plants should be spaced approximately 3 feet apart. It has a low canopy. It grows at a medium rate, and under ideal conditions can be expected to live for 40 years or more.
This shrub does best in full sun to partial shade. It prefers to grow in average to moist conditions, and shouldn't be allowed to dry out. It is not particular as to soil type or pH, and is able to handle environmental salt. It is somewhat tolerant of urban pollution. This is a selected variety of a species not originally from North America.
Blue Cape Plumbago makes a fine choice for the outdoor landscape, but it is also well-suited for use in outdoor pots and containers. Because of its height, it is often used as a 'thriller' in the 'spiller-thriller-filler' container combination; plant it near the center of the pot, surrounded by smaller plants and those that spill over the edges. It is even sizeable enough that it can be grown alone in a suitable container. Note that when grown in a container, it may not perform exactly as indicated on the tag - this is to be expected. Also note that when growing plants in outdoor containers and baskets, they may require more frequent waterings than they would in the yard or garden.
