With its small purple flowers the Jacaranda is a plant native toSouth America and Central. It can be used to decorate city streets, if placed in the ground, or even in gardens, in the ground or in pots. Let's get to know this fast growing plant better by understanding how to best grow it.
Belonging to the family of Bignoniaceae, classically cultivated in Paraguay, Argentina and Brazil, Jacaranda is a genus of plants that belongs to the Bignoniaceae family, a family that includes 49 species, all native to the tropical and subtropical regions of South America, Central America but also South Africa and of the Caribbean.
This plant grows very fast and is excellent in urban contexts as well as in gardens, it also manages to reach heights of 20 meters and at diameters of 30 centimeters. Its leaves are very large and green, composed of a series of smaller pointed leaves, with an elongated shape, simply pinnate, or pen-shaped, therefore with a central stem and lateral leaflets, in some species, but doubly pinnate in others .
In spring this plant is filled with flowers, small, up to 5 centimeters, and purple in color. Their shape is tubular, they are hermaphroditic and they join in terminal panniculi. If we look more closely, each flower has the shape of five lobes confluent in a long tube, with a corolla of a color ranging from blue to purple; some species have white flowers.
As the days go by they leave space to fruits, brown, flat oval or rounded elongated capsules, important above all due to the fact that they contain the seeds, winged seeds.
Very often we call with the name of the genus a particular species that is part of it, the Jacaranda mimosifolia, the best known plant and which we can also hear called Blue Jacaranda. The Italian name recorded by the vocabulary is iacaranda, to be precise. One of the reasons why we hear about this plant in our area is linked to the wood that is obtained from it, a highly appreciated and valuable wood, used for making furniture. We can hear it called Rosewood but it is not the correct name.
Although not native to our areas, this plant is not difficult to grow in our area and does not require special care. The Mediterranean climate is not difficult to tolerate: the Jacaranda it tolerates both very low winter temperatures and hot summer temperatures well. Of course, it is necessary to be careful that sudden frosts do not arrive: when it reaches zero degrees, or even lower temperatures, there could be damage to the plant.
Used to a humid environment, the Jacaranda requires a lot of water. Watering is therefore excellent all year round but especially in spring and summer, while in autumn and winter they must be done in moderation but never interrupted because the plant needs a certain degree of humidity. To encourage its growth, we can also take showers, which are also useful for eliminating the fronds and allowing the plant to breathe.
The best time to fertilize the plant is spring, as soon as it wakes up after vegetative rest. We always proceed in spring, therefore, and with a certain regularity, administering the mixture mixed with the watering every two weeks. At other times of the year it is not correct to fertilize, the recommended product must be rich in nitrogen, potassium, phosphorus, iron etc.
Always and only in the spring season, the time for repotting arrives, which does not necessarily have to be done every year. We must evaluate ourselves according to the pace of growth, trying to understand if the time has come to give Jacaranda a bigger "home". Let's take a pot with a maximum diameter of thirty centimeters and also use the same soil but being careful to change the most superficial layer of the soil with fresh, fertile soil mixed with sand, in such a way as to offer excellent drainage during watering.
The flowers of the Jacaranda they appear at two times of the year, in spring, as often happens, and also in autumn. In these seasons we can certainly exhibit it in the garden. It is not even necessary to prune it, in general, because it can grow regularly. However, there are times when it needs to breathe and it becomes necessary to let the leaves breathe.
Not for pruning but for commercial use, this plant can be cut. Its wood in Italy it is used for furniture but in South America, and not only that, it is also used to make some musical instruments such as guitars and pianos. In some cities, especially in Andalusia, this plant is found to embellish the streets of the city even if it can create logistical problems. Its seeds, very abundant, and its flowers, can clog the drains if the trees of this same species are concentrated in a small area.
