Some species of bulbous plants belong to the genus Scilla, originating in Europe, the Mediterranean area, Asia, the Middle East and southern Africa. These are generally small plants, which do not exceed 20-30 cm in height, with foliage of various sizes, and white or blue flowers, which bloom singly or in inflorescences of different sizes, depending on the species.
In the nursery are generally found European species, which are quite common also in cultivation.
these are easy-to-grow bulbous plants, many species can easily be used for the wild, and tend to produce ever-wider patches of leaves and flowers every year. There are also Mediterranean species that don't like cold, let's grow them trying to give them some extra care.
Many are the rustic species found in nurseries, such as Scilla siberica (of Asian origin), S. bifolia (single flower), S. litardierei (of Balkan origin). These are fairly small bulbous plants, which like sunny areas in cool climate periods, prefer half-shade in summer, or in any case when the climate is very hot and dry.
They settle in a good rich and fresh soil, at a depth of about twice the diameter of the bulb.
These species do not produce large inflorescences, it is therefore advisable to place the bulbs in spots, so as to obtain a richer flowering.
These are rustic plants, which do not fear the winter cold; it can happen that they are ruined by excessively dry summers, so it is good to have the foresight to place them at the feet of shrubs or taller flowering plants, which can guarantee a little shade on very hot and sultry days.
There are also cultivars and hybrids, with very large flowers, inflorescences with many flowers, or particular colors, such as cerulean blue.
There are some species of this genus that fear frost; the most commonly diffused is Peruvian Scilla; despite its name, this semi-evergreen bulbous is native to Africa. Loves sunny locations, good spring humidity; it tolerates drought well, but it is advisable to water it in case of scarce rains during flowering, to favor the luxuriance of the plant.
The bulbs are quite large, and are usually planted singularly, not too deep, but not too close to the surface, to prevent the cold from ruining them.
They produce large leaves with a fleshy appearance, and huge inverted cone inflorescences, which can count hundreds of small flowers, which bloom in succession starting from the base of the inflorescence. This variety is diffused in the intense blue color and also white, with the flowers mottled with green.
Scilla - Scilla: Peruvian scilla cultivation
Despite its exotic appearance, it is an easy-to-grow bulbous plant which, however, cannot stand frost, especially if it is intense or very prolonged.
If we live in an area with very cold winters it is therefore good to put our scilla bulb in a good-sized vase, so that it can be exposed outdoors in spring and summer, and stored in a cold greenhouse in winter. Not having a cold greenhouse we can also simply find a corner on a terrace that is well exposed to the sun, near the walls of the house, so that the plant is not completely exposed to wind and weather.
