There are also a great many hybrids and crosses available of these tropical plants.
Alocasia Plants Answer to the Name “Elephant’s Ear”
All Alocasia varieties are commonly called Elephant’s Ear because of the shape of the often tremendously large leaves. However, you will also find that some of the other common names associated with this plant are interchangeable from species to species.
Alocasias are members of the Araceae (aka aroid or arum) family of plants. They are herbaceous perennials, winter hardy in USDA hardiness zones 8B through 11.
Growing Details on Alocasia Plants
In their native settings, the tubers of some Alocasia are an important food source. The leaves of some types are also edible but must be properly cooked to neutralize the toxic calcium oxalate crystals they contain. No matter what kind of Alocasia you have, keep it out of the reach of kids, pets, and livestock.
In cooler climates, Alocasia can be planted in the landscape as annuals. Otherwise, they are lovely in an above-ground planter or as container plants in areas where they will not survive the winter.
If well-controlled, these aggressively spreading plants may be planted and naturalized or used as a groundcover in areas where they will survive winter.
There are many different sizes and colors to choose from among Alocasia species. Larger plants make stunning focal points and bring a strong tropical statement to any landscape.
Smaller varieties can be planted en masse as a groundcover or as edging surrounding a patio or along a border walk.
Leaf sizes range from small narrow leaves to large leaves 3′ feet across.
Alocasia Varieties With Brief Descriptions
Below are 20+ of the most frequently sought-after species, varieties, and types of Alocasia to grow and collect.
The popular Alocasia Amazonica is a cross between two Asian species – Alocasia longiloba x Alocasia sanderiana. The hybrid name comes from the nursery – Amazon Nursery – where the cross was made back in the 1950s.

- Foliage:The plants’ large green leaves display dramatic white veining and lighter secondary veins with wavy edges.
- Size & Growth:This variety may grow to reach about three feet high with a spread of approximately two feet.

Foliage:Purple Sword’s leaves are long and lance-shaped with slightly ruffled edges. They are deep green with a purplish hue.
Alocasia Calidora – Persian Palm
- Size & Growth:Calidora has a V-shaped growth habit, resulting in a footprint of about two feet with a top spread of about six feet. The plant grows to be between five and nine feet high. [source]
- Flowering:Persian Palm produces large cream-colored spadices in green sheaths in the springtime. The sheer size of the blooms (banana-sized) makes them a great point of interest for the plant. When left to mature, they transition into attractive, pyramid-shaped clusters of red berries.
