The Elephants’ ear Regal Shield has large leaves and grows via underground rhizomatous. These houseplants generally grow to be between three and six feet tall.

The plant’s leaves are also very large and grow to between eight and twenty inches.

Alocasia Regal Shield plants are generally grown for their lovely foliage. However, they can flower if kept in the right conditions. This plant produces white or pale yellow flowers if the weather is warm enough. They also become dormant during the winter and start to drop their leaves.

Caring for an Alocasia Regal Shield Plant

Alocasia Regal Shield Care

Alocasia Regal Shield plants are very easy to look after; you just need to keep them in a well lite area and provide the correct amount of water. Here’s how to care for your plant:


You can water your Alocasia Regal Shield plant thoroughly and then leave it to dry out before watering again. Always touch your plant’s soil to see if it needs water, and be careful not to overwater your plant. Overwatering can lead to issues such as root rot and fungal infections.

In hot weather, your plant will likely require extra water. Your plant will need more water during the growing season, and you may need to water up to three times weekly in the summer.

Sunlight and Temperature

The Alocasia Regal Shield loves to live in medium to bright sunlight but shouldn’t be left in the direct sun for too long. They can be successfully grown on a windowsill. The plant will naturally grow towards the sun and can become unbalanced if it’s not rotated regularly.

If you’re planting your Alocasia Regal Shield outside, it’s best to find a well-lit area that has indirect sun. Don’t plant in the fierce sun as the leaves can get burnt. It’s best to grow the Alocasia Regal Shield in temperatures of between 55 and 80 °F. These plants don’t like cold weather, so you may need to move the plant into your home or a greenhouse in the fall.


Alocasia Regal Shield plants prefer well-drained soil which is rich in nutrients. You can use houseplant potting mix, which is quick-drying and has a PH range of between 5.5 and 7.0.


Alocasia Regal Shield also loves being in climates with high humidity. Ideally, the moisture levels in the air should be over 80%. If you live in a drier climate, you can use a mister or humidifier to add moisture to the atmosphere.

Use a spray bottle to mist your plant’s foliage twice weekly. Be careful not to overdo it, as plants that are left with damp leaves are prone to fungal infections. Alternatively, you can put a pebble-water tray under your plant’s pot. Placing two or more plants close together also helps to improve humidity.


Alocasia Regal Shield plants can be given a houseplant fertilizer about once every month during the growing season. Use a good quality product and always follow the manufacturer’s instructions. In most cases, liquid fertilizers can be mixed into the water when you water your plants.

Your plants don’t need fertilizer when it’s cold, and they’ve stopped growing, so don’t provide fertilizer in the fall or winter.

Problems that affect the Regal Shield Plant

There are a few problems that you may experience when growing this plant. These plants are often affected by spider mites and can go dormant if they get too cold, which results in leaf loss. Here are some of the most common issues and how to care for your plant:

Leaves Turning Yellow

It’s not normal for lots of leaves to quickly turn yellow or drop off. This will happen if you overwater your plant. If you notice leaves starting to turn yellow, it’s best to adjust your watering schedule.

Brown Spots on the Leaves or Brown Edges

If the leaves begin to turn brown, it’s likely to be caused by dry soil or low humidity. You may need to start misting your plants to improve humidity. Other ways to improve humidity include grouping tropical plants together, putting a pebble-water tray under your plant’s pot, or using a room humidifier. Plants often drop their leaves due to low humidity.
