Banana del Paranà - Asimina triloba

Banana del Paranà

A medium-sized tree native to the eastern United States, Asimina triloba, also known as the paranà banana, reaches 7-8 meters in height, developing very slowly. It has a short stem, from which many large branches branch off, which divide in a rather disordered way, but giving rise to a fairly rounded crown; the large leaves are oval, leathery, in autumn, before falling, they become golden-yellow. Before the leaves, at the beginning of spring, large red-brown flowers bloom on the one-year-old branches, from which the fruits, similar to bananas, 10-15 cm long, gathered in groups of three or four will originate; the fruits are edible, have a creamy pulp, with a sweet taste, similar to banana and pineapple. By many this plant is also referred to as a mountain banana because of its fruits similar to bananas in shape and flavor that ripen even at altitudes typical of the mountain horizon.


As for exposure to the sun's rays, the young specimens of Paranà banana trees need to be placed in semi-shaded places, while adult trees prefer full sun. These trees, with a very exotic and tropical appearance, do not fear the cold and can withstand temperatures close to -20 ° C. Their optimal resistance to freezing makes them perfect for harsh climates and for areas of northern Italy where temperatures can drop well below zero in winter.

  • Mountain banana

    The mountain banana is a very particular tree, but pleasant both for the appearance and for the fruits with different characteristics from the classic banana. Prefers fertile, fresh, draining soil ...


Mountain banana plants can be satisfied with the rains, although it is good to water the young specimens in hot periods of the year, especially in case of prolonged drought. In the winter months, however, watering must be suspended to avoid dangerous water stagnation. The mountain climate, with frequent rainfall in summer and in the warmer months, is very suitable for the growth of these species.


As for the soil, the asimines prefer soft, well-drained soils, rich in organic matter. These trees produce numerous suckers, which it is good to eradicate for a good development of the plant and to prevent these secondary branches from taking away energy from what is the central trunk of the Asimina.

The characteristics of the ideal soil for the plant can be justified by taking into account its natural habitat of origin. Coming from alluvial plains or developing near streams and streams, the paranà banana grows optimally where the soil is loose, full of debris and silty.

A type of soil that the plant does not tolerate is the calcareous one.


The multiplication of these plants occurs by seed, while the agamic multiplication is very difficult because the cuttings do not produce roots. One aspect to take into consideration is that if not sown immediately, the seeds must be buried in moist soil and exposed to winter temperatures or even in the refrigerator. The young plants must be cultivated for at least a couple of years in pots, and then they are planted taking care not to touch the earth around the roots. As for the cuttings, this usually does not take root.

Often, when it is decided to reproduce the plant, plants with the same characteristics as the original ones are not obtained and they also generate fruits (in most cases), of lower quality.

Parasites and diseases

Asimina triloba specimens are generally not attacked by parasites or diseases.

However, we can talk about some particularities of the plant.

The banana of the paranà is a toxic species (without taking into account the fruits of the plant which are edible). This is because it contains substances with antimitotic activity and following in-depth studies it was discovered that these substances could be used in the treatment of turmoors.

To underline once again, the toxicity of the plant. In fact, some people would show allergic reactions to contact with the leaves of this species.

The plant has no particular problems with parasites and diseases also because, thanks to its strength and resistance, it does not require any type of treatment.
