Caducous climbing shrub native to Africa, some species of plumbago are native to southern Europe. It has thin, semi-woody stems, which can reach lengths close to 1.5-2 meters, but which are usually kept more compact with autumn pruning; the leaves are oval, fairly small, pointed, light green in color, thin. From June to the early colds it produces numerous umbrella inflorescences made up of five-petal trumpet flowers of a characteristic sky blue color. It is advisable to prune the plant at the end of flowering to obtain a greater quantity of flowers the following summer. The Alba variety has white flowers, the Royal Cape cultivar has cobalt blue flowers.
The plumbago it is a very common shrub in cultivation: its trump cards are the vigor, the long flowering season and the color of its corollas, a pure and lively light blue, very difficult to find in other plants. To maintain this sarmentosa over the years it is essential to take care of its pruning, to carry out punctual repottings and, almost everywhere in our country, to protect it from low winter temperatures with special materials or by withdrawing the pots.
Origins and description
The plumbago (Plumbago capensis, of the Plumbaginaceae family), also called plumbago or blue jasmine, is a sarmentose native to South Africa, in particular from the area of the Cape of Good Hope (from which it takes its name capensis). It is by far the most widespread in cultivation, even if the genus includes about ten species, different in size, colors and bearing.
It is a shrub that, in our country, can reach 4 meters in height (in tropical climates it easily exceeds 6), with woody and semi-climbing stems. The leaves are whole, oblong and with a smooth lamina, of a nice light green. From April-May it carries large umbrella-shaped inflorescences composed of many flowers with petals and sky blue antene.
