Cape plumbago can be grown as an annual, or in a container as a perennial, that is brought indoors and placed in a bright sunny room for the colder months. Water container plants sparingly in the winter. If treating as a perennial, cut back in late winter to encourage new growth for the upcoming season. It can also be cut back in the winter and stored in a cool, dark environment. The white, blue or pink flowers are in a terminal cluster, tubular, 5-parted with spreading lobes. In the right environment, it will flower year-round. Although technically a shrub, with a little assistance it can be trained to perform like a vine. Its arching branches will need tying. If the plant becomes leggy, it can be cut back to control. It has a suckering habit. Insects, Diseases, and Other Plant Problems: It can cause contact dermatitis so wear gloves when handling the plant. More information on Plumbago .
