Do you want to add a unique and eye-catching addition to your home? The purple waffle plant is an exotic-looking houseplant perfect for any home. This article will cover everything you need to know about growing and caring for a purple waffle plant, including essential light and soil requirements, how to propagate the plant, and potential pests and diseases. Let’s get started!

What Is a Purple Waffle Plant?

This stunning and unique plant is part of the Acanthaceae family and is native to tropical regions of Asia and Africa. It has bright lilac-purple leaves that give it a truly eye-catching look. Plus, it requires minimal care and does well both indoors and outdoors.

The Purple Waffle Plant is a perennial herb that grows in clusters and can reach heights of up to two feet. Its leaves are densely arranged around its branches and are a unique deep purple color. The leaves are typically heart-shaped and quite thick, giving them a waffle-like texture. The flowers of the Purple Waffle Plant are white or yellow and have five very fragrant petals.

How to Grow a Purple Waffle Plant

Growing and caring for a purple waffle plant is a great way to add vibrant color and lush foliage to your home. The name purple waffle plant comes from the beautiful purple-green leaves that form a waffle pattern. These plants are easy to care for and add significantly to any interior decor.

Light Requirements

This plant needs bright, indirect light but can tolerate lower light levels. If you are worried about low light levels, you can supplement with a grow light. The purple waffle plant won’t thrive with too much light, so keep the plant away from direct sunlight. It’s best to choose a location for the purple waffle plant that is in medium light.

You should also be aware that the amount of light the purple waffle plant needs will change throughout the year. In the summer months, give the plant more light; in the winter months, give it less. The leaves turn a beautiful deep purple color when giving the plant enough light. If the purple waffle plant isn’t getting enough light, the leaves will become lighter in color and won’t be as vibrant.

Soil Requirements

They prefer well-draining, rich potting soil with a low pH (6.0 – 6.5) high in organic matter. This type of soil will provide the nutrients the plant needs to thrive. Additionally, if you are growing your purple waffle plant in a container, you can use a commercial potting soil such as Miracle-Gro® Indoor Potting Mix for best results.


To do this, start by carefully digging up the plant. The root ball should be soaked in water for about an hour before division. With your hands, gently separate the root ball into sections, keeping as much of the root system intact as possible. Plant each division into a separate pot or container filled with well-draining soil. Water the newly planted division, and keep it in a warm and sunny location.

Young Purple Waffle Plant can also be propagated through cuttings. To take a cutting, select a healthy-looking stem from the parent plant and snip it off with scissors. Remove any leaves from the cutting, leaving just the bare stem. Dip the end into a rooting hormone and plant the cutting into a pot filled with moist, well-draining soil. Water the soil and keep the cutting in a warm, sunny location.

Caring for a Purple Waffle Plant

Caring for a purple waffle plant is a delightful task for those with a green thumb. These plants are native to tropical regions, like South Africa and Southeast Asia, so they thrive in warm, humid conditions. When the proper care is taken, these plants bear stunning foliage with lovely purple hues and waffle-like leaves.

Watering Needs

Watering needs for a purple waffle plant are straightforward, but it is still essential to get it right. Firstly, water sparingly. A purple waffle plant is quite tolerant of drying out between watering, so don’t feel you need to water it daily. The best rule of thumb is to water it when the top few inches of the soil start to feel dry.

It is also essential to ensure that you use the right amount of water when you water the plant. The best way to determine this is to use the load test. Put some soil in a cup and add enough water to fill it halfway. If the soil starts to float, there is too much water; if the soil sinks, you need to add more water.

Finally, make sure you use lukewarm water and avoid cold water, as this can shock the plant. Once you have watered the plant, it is also important to let any excess water drain away, as this can help prevent root rot.

Fertilizing Requirements

A good rule of thumb is to fertilize your plant every four to six weeks during the growing season and once or twice during the dormant season.

When fertilizing, use a balanced fertilizer and mix it according to the instructions on the package. Be sure to apply it to the soil, not the plant. You can dilute the fertilizer with water if you apply it directly onto the leaves and stems.

It is best to use a slow-release fertilizer or organic compost during the growing season. This will provide your purple waffle plant with all the nutrients it needs. If your soil does not have enough nutrients, you can also use a liquid fertilizer that you can apply every two weeks. This can help ensure that your plant has access to all the necessary nutrients.

Finally, monitoring the soil around your plant is essential to ensure it is not becoming too dry or too wet. If the soil becomes too dry, add some water to it until it reaches the desired moisture level. On the other hand, if the soil is too wet, adding some organic matter, such as compost, may be necessary to help absorb some excess moisture.

Potential Pests and Diseases

Unfortunately, even the hardiest of plants are vulnerable to pests and diseases. The good news is, with little knowledge, most of these issues can be taken care of quickly. When it comes to the purple waffle plant, the most common issues are mealybugs, fungus gnats, and root rot.

Mealybugs are tiny white bugs that can quickly ruin a purple waffle plant’s beautiful leaves. The best way to spot them is to look for cottony masses on the leaves or stems or minor white bugs on the leaves. You’ll need to take action immediately if you see any of these signs. The best way to get rid of mealybugs is to apply neem oil or another insecticidal soap to the affected area.

Fungus gnats can also cause problems for a purple waffle plant. These pests hover around the soil surface and look like tiny little flies. They can cause the plant to become stressed out and can even cause root rot if left unchecked. To get rid of fungus gnats, you’ll need to remove the infested soil and replace it with new soil.

Lastly, a purple waffle plant can suffer from root rot, a fungal disease that causes the plant’s roots to rot. If you notice that the base of the stems of your Purple Waffle Plant is soft and mushy, that can be a sign of root rot. You’ll need to remove the affected roots and replant the plant in new, sterile soil to get rid of root rot.


Growing and caring for a Purple Waffle Plant is a fun and rewarding task. With suitable soil and light requirements, these plants can thrive and add a unique and vibrant color to any room. They’re easy to propagate and make excellent gifts for family and friends. The Purple Waffle Plant can become a treasured addition to your home with proper watering and fertilizing needs and occasional pest control.

Though the Purple Waffle Plant isn’t the most well-known houseplant, those who choose to grow and care for one will surely be rewarded with a beautiful and unique addition to their home. It will bring color and life to any space with just a bit of care.
