Overview of the Plant

Common and Vernacular Names

Colocasia esculenta is commonly known as Taro, Elephant Ear, Cocoyam, Eddo, and Dasheen. The Hawaiian Punch cultivar is also known as Purple Taro, Hawaiian Taro, and Kalo.

Description of the Plant

Colocasia esculenta is a herbaceous perennial that can grow up to 6 feet tall and 3 feet wide. It has large, arrow-shaped leaves that can be up to 3 feet long and 2 feet wide.

The leaves emerge from a central stem and sit on long petioles that attach to the corm. Hawaiian Punch has deep purple leaves with green veins, which intensify with more sunlight.

Colocasia esculenta produces a spathe and spadix inflorescence, which resembles a small hooded flower. The inflorescence is not the main attraction of the plant, but it is interesting from a botanical perspective.

The spathe is usually greenish-yellow, and the spadix is white or yellowish.


Colocasia esculenta is known for its starchy and nutritious corms, which are a staple food in many tropical countries. The corms are an excellent source of carbohydrates, fiber, vitamins, and minerals.

Taro leaves are also edible and are used in soups, stews, and curries. Hawaiian Punch is a popular ornamental plant that is prized for its unique and attractive foliage.

Its deep purple leaves contrast beautifully with the green veins and make a dramatic statement in any garden. The leaves are also an excellent backdrop for other colorful plants, such as hibiscus, bird of paradise, or plumeria.

Colocasia esculenta is known to attract pollinators, such as bees and butterflies. The inflorescence provides a source of nectar and pollen for these important insects.

The leaves of taro plants also provide shelter and habitat for small animals such as frogs, lizards, and insects.

Plant Cultivation and Care

Preferred Growing Conditions

Colocasia esculenta prefers warm and moist climates, with temperatures ranging from 68 to 86 degrees Fahrenheit. It can grow in full sun to partial shade but will do best in a location with dappled sunlight.

Hawaiian Punch requires well-draining soil that is rich in organic matter. The soil pH should be between 5.5 and 6.5.

Taro is a water-loving plant and requires consistent moisture to thrive.

However, it is important not to overwater the plant, as this can lead to root rot. It is best to keep the soil moist but not waterlogged.

Taro can be grown in containers or in the ground. If growing in a container, make sure to use a pot with drainage holes and water regularly.

Potential Pest and Disease Issues

Colocasia esculenta is generally pest and disease resistant but can be susceptible to a few issues. The most common pests are aphids, spider mites, and mealybugs.

These pests can be controlled with insecticidal soap or neem oil. Taro can also be affected by fungal diseases such as leaf spot, powdery mildew, and root rot.

These diseases can be prevented by ensuring good air circulation, avoiding overwatering, and removing infected leaves.

Planting and Maintenance Tips

To plant taro, dig a hole that is two to three times the size of the corm and fill it with rich, well-draining soil. Place the corm in the hole, making sure that the top is level with the soil surface.

Water the plant thoroughly and continue to water regularly to keep the soil moist. Fertilize the plant every 4-6 weeks with a balanced fertilizer.

To maintain the plant, remove any yellow or damaged leaves as soon as possible. This will help to prevent the spread of diseases and pests and promote healthy growth.

Also, make sure to mulch around the base of the plant to retain moisture and suppress weeds.


In conclusion, Colocasia esculenta ‘Hawaiian Punch’ (Taro) is a beautiful and valuable plant that is both ornamental and functional. It is easy to grow and care for and provides a source of nutrition, culture, and habitat.

By following the preferred growing conditions and planting and maintenance tips, you can enjoy this stunning plant in your garden or on your plate.

Plant Propagation Methods

Colocasia esculenta ‘Hawaiian Punch’ (Taro) can be propagated by both sexual and asexual reproduction methods. Sexual reproduction involves the use of seeds to produce new plants.

Taro produces small, greenish-yellow flowers that give rise to the seed-bearing fruit. The fruit is a fleshy, berry-like structure that contains one or two seeds.

The seeds must be carefully collected and cleaned before planting. Taro seeds can be directly sown into prepared soil, or they can be started in a nursery bed or greenhouse.

The seeds should be lightly covered with soil and kept moist until they germinate. It can take several weeks to several months for taro seeds to germinate, depending on the growing conditions.

Asexual reproduction involves the use of vegetative parts of the plant to produce new plants. Taro is well-suited for asexual reproduction because it produces multiple corms that can be divided and replanted.

To propagate taro by division, carefully dig up the plant and separate the corms with a sharp knife. Each corm should have at least one eye or sprout.

Then, plant the corms in prepared soil with the sprouts facing up. Water the soil well, and maintain consistent moisture until the new plants are established.

Plant Adaptations to Different Environments

Colocasia esculenta ‘Hawaiian Punch’ (Taro) has several adaptations that enable it to thrive in diverse environments. One adaptation is its ability to grow in flooded and waterlogged soils.

Taro has a large number of adventitious roots that arise from the corm and grow upward toward the soil surface. These roots enable the plant to absorb oxygen and nutrients from the water and soil, even in anaerobic conditions.

The leaves of taro plants are also hydrophobic, meaning they repel water, which helps them to shed excess water and prevent disease. Another adaptation is the ability of taro to grow in a variety of soils.

Taro can grow in soil that is both alkaline or acidic and can tolerate soil that is heavy in clay or sand. However, the best soil for taro is well-draining soil that is rich in organic matter.

Taro also has adaptations that help it to conserve water in dry conditions. The leaves of taro plants have a waxy cuticle that reduces water loss through transpiration.

The plant can also reduce the surface area of its leaves when water is scarce, which conserves water and energy. Moreover, taro has adaptations for protection from herbivores and environmental stressors.

The leaves of taro plants contain calcium oxalate crystals that deter herbivores from consuming them. These crystals can also help the plant to defend against damage from wind, hail, and other environmental stressors.

In summary, Colocasia esculenta ‘Hawaiian Punch’ (Taro) has several important adaptations that enable it to thrive in different environments. By understanding these adaptations, gardeners can make informed decisions about how to grow and propagate taro plants.

Whether grown for ornamental or culinary purposes, taro is a valuable and fascinating plant that deserves our attention and care. Usage of Colocasia esculenta ‘Hawaiian Punch’ (Taro) in Indoor Settings

Colocasia esculenta ‘Hawaiian Punch’ is particularly suited for this, as its deep purple leaves add a striking contrast to any indoor space. To grow taro indoors, start by finding a location with bright, indirect sunlight.

Taro can also grow well in artificial light conditions and can be grown under grow lights. The plant thrives in warm and humid conditions, so maintaining a temperature range between 68 to 86 degrees Fahrenheit is ideal, along with 50-75% humidity.

A well-draining potting mix that is rich in organic matter can be used to grow taro plants in containers. Pot sizes can be selected based on the growth rate of the plant, and larger pots can be used for mature plants.

Taro should be watered regularly and kept consistently moist but not waterlogged. Adequate drainage is important, as taro does not like to be sitting in water.

Regular feeding with a balanced fertilizer can also promote healthy growth. Taro plants can benefit from frequent misting to maintain humidity, but care should be taken not to wet the leaves or corm.

The leaves should also be cleaned regularly to prevent dust and pests from accumulating. In addition, taro plants can be propagated by division, allowing for new plants to be grown easily.
