Alocasia is a genus of rhizomatous or tuberous plants in the greater Araceae family. They are distinguished by their large cordate – with their leaves growing 20-90 centimeters in length.
Many species in the Alocasia genus are toxic as they contain raphide crystals (that constrain calcium oxalate) that can inflame and numb the tongue and throat – causing difficulty in breathing and pain.
Currently there are 90 or so accepted species that are classified within the Alocasia genus. As houseplants, they have gained increasing popularity – especially over the past few years.
When grown indoors, they do require proper lighting, high moisture, and fertilization – tending to do quite well in the greenhouse setting. Rarely are they able to withstand cold winters (or the drying effects of your home’s heating system) – and oftentimes they go dormant during the colder seasons, only to grow back in the spring and summer. Specific care instructions will depend largely on the species of Alocasia.
