The huge, arrow-shaped, occasionally round leaves seem to be mostly green and have notable capillaries. Cultured plants almost never blossom. If eaten fresh, all parts of the plant may cause nausea and vomiting, and the sap may damage the skin.

The plant thrives in partial shade or screened sunlight, as well as wet, fertile soil. It must not be left to dry out and can be kept out of the way of heavy winds. The plant can spread and be split in the same way that other perennials with storage organs can.

This plant has a tropical appearance in pleasant planting areas, especially at the rim of a tree’s underbrush or in a boundary. It is also suitable for growing as a sample plant. It is also suitable for growing as a potted plant. It could also be used as a houseplant outside in the hotter seasons and taken inside during the cold months.

Main Differences Between Alocasia and Colocasia

  1. The Alocasia leaf is oriented horizontally. The leaf’s twigs, or petioles, can be seen extending into the leaf. As a result, the majority of Alocasia leaves juncture up instead of down. Petioles of Colocasia, on the other hand, attach from rungs in the leaf. That is why leaves appear to fall or hang straight down.
  2. The leaves of Alocasia are very shiny or rubbery in presentation, with notable arteries. They have an arrow-shaped and a heart-shaped leaf, whereas Colocasia has matte green leaves that are somewhat spherical in their shapes.
  3. Alocasia needs to grow in the dark, but Colocasia needs the sunrays to bloom. 
  4. Most parts of Alocasia are poisonous, whereas Colocasia does not have many dangerous properties. 
  5. Alocasia can produce rhizomes and tubers, but Colocasia can only produce tubers. 


Both Alocasia, as well as Colocasia, are recognized as ‘elephant ears.’ They are both members of the ‘Araceae’ household. Both plants are well-known for their broad leaves, that are referred to as elephant ears.
