Mimosa

The mimosa (acacia dealbata) is a tree originating from Tasmania, but which, arrived in our country in the mid-1800s, has adapted very well to the climate of the Ligurian Riviera and that of the southern regions and large lakes: it has even part of the landscape of these places thanks also to the bursting bloom which, among the earliest, announces the arrival of spring.

Mimosa is native to the Australian continent. In Italy they resist well in the temperate climates of central and southern Italy, but they can also be grown on the coasts of the great lakes of the north, where they can benefit from milder temperatures. Cultivation in other areas must be done in pots or greenhouses.

There mimosa plant it can also reach considerable sizes. The leaves are composed of many leaflets placed perpendicular to the main rib. Some varieties do not have the classic leaves, but have transformed leaves, which are like flattened twigs, called phyllades.

The inflorescence is composed of a set of globular flower heads from which numerous stamens depart. The large quantity of flowers gives this plant a special charm.


Cultivation techniques

The ideal soil for flowering is basically acidic, with a good structure, which ensures good humidity, but at the same time good drainage. We recommend making organic matter (humus) periodically (once a year), both in order to guarantee the plant the right nutrient supply and to improve the structure of the soil. Mimosas with phyllodes are more resistant to low acid soils

The best time to plant the mimosa is from October to March. In colder areas it can be grown in a greenhouse with the foresight not to drop the temperature below 0 degrees. The pot needs to be changed about every two years. It should be remembered that the diameter of the pot must not increase excessively, both for an aesthetic factor and to maintain a correct proportion between the aerial and the root system.
