Alocasia Vs Colocasia: Detailed Differences
The table is short but compact. If you fail to understand anything from the table then you must read this section. Here I discussed everything vital in detail.
Differences In Leaf Shape and Appearance
- Alocasia: The Alocasia leaves are heart-shaped or arrow-shaped. These leaves have stunning colors and distinct patterns. For its color, Alocasia leaves have a separate fan base.
- Colocasia: Colocasia leaves are also heart-shaped, but their focus lies more in the variety of colors and patterns they display. The leaves are larger than Alocasia leaves. Their special feature is their various shades. These shades create an interesting visual impact.

Growth Habit and Size
- Alocasia: You must know the growth habit and their size differences before you buy any plant between these. Alocasia plants have a fast-growing, tropical nature. They can reach heights of 2 to 10 feet depending on their species. They grow quite rapidly. The growth rate increases during warm months.
- Colocasia: Colocasia’s growth rate is also noticeable. It tends to grow up to 6 feet in height. Various species of it have slightly different growth rates. Colocasia’s growth rate is very high but they might not match the rapid growth of some Alocasia varieties. If you like short plants to keep indoors, then Colocasia will be a good option.

Sun Exposure and Soil Type
- Alocasia: These plants prefer bright indirect light indoors and partial shade outdoors. They thrive in loose, well-draining potting mix and slightly acidic soil (pH 5.5 to 6.5).
- Colocasia: Colocasia can handle full sun to part shade conditions. They grow well in loamy, fertile soil without the specific pH requirements mentioned.
Toxicity In Both
- Alocasia: Here I have a caution for pet owners. The leaves of Alocasia are toxic to dogs, cats, and humans due to the presence of harmful compounds. But not too much harmful to kill them.
- Colocasia: All parts of Colocasia are initially poisonous when raw, but the tubers become edible after cooking. This is a significant difference, as Colocasia tubers have culinary uses in some cultures.
Winter Care Differences
- Alocasia: Alocasia becomes dormant during the winter. For this nature, you need to keep this indoors in warm and humid conditions. That temperature is its native tropical habitat.
- Colocasia: Depending on the climate, you may treat Colocasia in either way. It can be annual or overwintered. If you live in a colder zone, dig up the tubers after the first frost and store them in a cool, dry place to protect them from temperatures below 65°F.
Landscape Use
- Alocasia: Alocasia is both an indoor and outdoor plant. So, you can keep it in both places. Its unique leaf shapes, colors, and patterns add an exotic touch to gardens and interiors.
- Colocasia: Colocasia serves as an accent plant. People often use it to enhance landscapes or container arrangements. You can also place it in both places.
