Colocasia esculenta ‘Black Magic,’ also known as Taro, is a stunning plant with glossy, black leaves that adds a unique touch to any garden. This plant can grow up to six feet tall and three feet wide, making it an excellent choice for creating a dramatic focal point in a garden bed.

In this article, we will go over the plant’s characteristics, how to grow and care for it, and its potential pest and disease issues.

Overview of the plant

Colocasia esculenta ‘Black Magic’ is a member of the Araceae family and is originally from the tropical regions of Southeast Asia and India. This plant goes by different names, including Elephant Ear, Ape Plant, and Eddo.

The leaves of the Taro plant can grow as large as two feet long and are deep, glossy black in color with a velvety appearance, giving it a dramatic presence in a garden bed. The plant has a beautiful purple stem, and when it blooms, it produces a flower that is yellowish-green in color that stands out from the darkness of the leaves.

The flower is uncommonly seen in cultivation because, in most cases, growers are looking to maximize leaf production.

Characteristics and benefits to wildlife

Aside from the plant’s aesthetic appeal, it has several benefits to wildlife. The Taro plant serves as a host for the Pink-Spotted Hawk Moth caterpillar and gives them a place to feed and grow.

The mature leaves of the Taro plant also provide shelter for amphibians, which use them to cover themselves during the day. With its large leaves, the plant can shade the soil, prevent soil erosion, and improve soil health due to its high moisture retention.

Plant cultivation and care

Preferred growing conditions

Before planting the Taro plant, it is essential to ensure that the soil is fertile and well-draining. The plant prefers soil that is rich in organic matter and consistently moist, but not waterlogged.

The plant requires bright, indirect light and warm temperatures to thrive, and it is sensitive to the cold, so it should be put in a sheltered area.

Potential pest and disease issues

A healthy Taro plant is relatively pest and disease-free. The most common problem with the Taro plant is root rot, which is caused by overwatering and poor drainage.

To prevent this problem, ensure that the soil is well-draining and never waterlogged. Diseases such as leaf spot and stem rot can also occur in the Taro plant, but these problems mainly arise due to poor cultural conditions, including high humidity and poor air circulation.

Planting and maintenance tips

Planting Taro is a simple process and involves digging a hole deep enough to accommodate the plant’s root system. The plant should then be placed in the hole and covered with soil, ensuring that the roots are spread out and covered entirely.

Water the plant thoroughly after planting, ensuring the soil is well damp. The Taro plant requires consistent moisture, so regular watering is necessary, especially during hot and dry weather.

Fertilize the plant every two to three weeks with a balanced fertilizer. It is essential to remove dead or yellowing leaves and prune back the plant to manage its size.


Colocasia esculenta ‘Black Magic’ brings an exotic touch to any garden with its attractive black leaves and striking appearance. By following the recommended care and planting tips and keeping an eye on possible pest and disease issues, you can have a beautiful and exotic-looking plant that is easy to grow and maintain.

Plant Propagation Methods

Colocasia esculenta ‘Black Magic’ is a versatile plant that can be propagated through both sexual and asexual means. Sexual reproduction involves seed production, while asexual reproduction involves vegetative propagation.

Here are some propagation methods that you can use to propagate your Colocasia esculenta ‘Black Magic.’

Sexual Reproduction (Seed Propagation)

Propagation through seeds is a time-consuming process, but it is the best way to create new and unique Colocasia plants. You can obtain seeds from the plant’s flower stalk after the blooming season.

It is important to allow the pod to become completely dry before removing the seeds to ensure high germination rates. Once the seeds are collected, you can plant them in a container filled with a mixture of peat, perlite, or sand to ensure good drainage and aeration.

Keep the soil moist, warm, and in bright and indirect sunlight. The seeds will germinate in two to four weeks.

Asexual Reproduction (Vegetative Propagation)

Vegetative propagation involves creating new plants from existing ones without the involvement of seeds. The benefit of vegetative propagation is that the offspring will be identical to the parent plant.

Here are some of the most popular methods of vegetative propagation. 1.


Division involves separating a plant into smaller sections, each with its roots. This method is best suited for mature plants.

To do this, dig up the plant and use a sharp knife or garden shears to cut the plant into several sections. Each section should have enough roots and leaves to establish itself in its new location.

2. Rhizome Cuttings

This method of propagation involves cutting off a section of a healthy rhizome and planting it in the soil.

The rhizome should be about four to six inches long, and the cutting should be made with sharp and sterilized garden shears. Ensure that each cutting has enough buds and roots.

3. Suckers

Suckers are small plantlets that grow from the parent plant’s main stem or roots.

To propagate through suckers, simply wait for the plantlet to produce roots before detaching it from the parent plant.

Plant Adaptations to Different Environments

Colocasia esculenta ‘Black Magic’ is native to the tropical regions of Southeast Asia and India, where it thrives in warm, humid, and boggy environments. Here are some adaptations that allow the plant to survive and thrive in different environments.

1. Water Storage and Retention

Colocasia esculenta ‘Black Magic’ can store water in underground stem structures known as rhizomes, making it more tolerant to drought.

The plant’s large leaves also help it to retain moisture, which is important in dry environments. 2.


Colocasia esculenta ‘Black Magic’ has specialized tissue called aerenchyma that allows it to survive in oxygen-deficient soils. The tissue creates air channels that allow oxygen to move from above-ground parts of the plant to the roots.

3. Shade Tolerance

Colocasia esculenta ‘Black Magic’ requires bright but indirect light, making it well-adapted to growing in partially shaded conditions.

In dense forest environments, the plant can grow towards the canopy of the forest to reach for sunlight. 4.

Reproductive Strategies

Colocasia esculenta ‘Black Magic’ can produce both seed and vegetative reproductions. This adaptability allows the plant to have multiple strategies for survival in different environments.

In conclusion, Colocasia esculenta ‘Black Magic’ is a striking plant that can be propagated through both sexual and asexual methods. Its adaptations allow it to survive and thrive in different environments, making it a popular choice for gardeners looking to add an exotic touch to their gardens.
