Plumbago

The plumbago plant (Plumbago auriculata), also known as the Cape plumbago or sky flower, is actually a shrub and in its natural surroundings can grow 6 to 10 feet (2-3 m.) tall with a spread of 8 to 10 feet (2.5-3 m.). It is native to South Africa and knowing this provides the first clue to how to grow plumbago, along with where to grow one.

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.
