Alocasia amazonica

The Amazon Alocasia is the typical plant you see in a nursery and want to take home so rare and beautiful it is. However, it is also one of the most complicated, as it does not resist cold at all, much less frost. If we leave the windows open or the heating/ fan on… we will harm it, a lot. To this we must add that it does not resist drought or waterlogging, and to be well it needs that the environmental humidity and the temperature be high. Taking all this into account, how is this plant cared for?

In this article we are going to explain all the characteristics and care of Alocasia amazonica.

Origin and characteristics

The Alocasia amazonica is a hybrid plant, and its scientific name Real Alocasia x amazonica. It is also known by the common name of elephant ear. This common name comes from the way they have their leaves. It grows to a height of 3-4 meters, although it is normal to stay at 1-2m. Its leaves are large, with a length of 20 to 90 cm, petiolate, dark green in color and with very visible white veins on the upper side, and darker on the underside. These leaves have an arrow-like appearance and are quite shiny. They are wide and bulging leaves and are pronounced in the silvery white color. Its edges are of the edged type in the same tone and are deeply lobed.

A curiosity about Alocasia amazonica is that the leaves on the underside are purple, have long petioles, and are approximately 40 centimeters long.

The flowers sprout at the end of a very short stem, which is usually not easily seen since they are usually hidden between the leaves. The corm (underground bulb), as well as the rest of the plant, are very toxic: they contain calcium oxalate crystals along with other irritants that apart from numbing the throat, swell the tongue and pharynx, thus making it difficult to breathe. You have to be careful with the flowers as having the scent can be attracted to animals or the little ones. Flowering takes place in summer and usually flowers only if grown outdoors. If you use it as an indoor plant, it is rare that it can flower.
