Many plants, spread across the globe, belong to the genus Solanum. Some are grown in the vegetable garden, such as Solanum melongena (eggplant), and others in the garden or on the terrace. In particular, in terrace pots, two species of Solanum are cultivated: Solanum Rantonnetii, a bushy species with purple flowers, and Solanum Jasminoides, a trailing or climbing variety with white or lilac flowers. These species of Solanum are of tropical origin, but they can remain outdoors all year round in areas with mild winters, and should be protected in areas with very cold winters. They prefer very sunny positions, and soil that is rich and well drained. During the winter, they lose a lot of their leaves, especially if the weather is cold. They are watered only when the soil is dry, as they tolerate drought very well, but fear stagnant water. Flowering is continuous throughout the summer, but to stimulate it, it is good, at the end of winter, to provide a fertilizer for flowering plants every 12-15 days, mixed with the irrigating water. It does not require drastic pruning, but in autumn or at the end of winter it is a good idea to shorten the longer branches, to avoid the plant becoming disordered.
