Calathea is a tropical plant also known as the Zebra Plant or Zebrina Plant (Calathea zebrina).
These plants are used mainly for their vibrant colorful leaves which include yellow, rose, white, and even olive.
Many people get Calatheas and Marantas confused. Both Calathea and Maranta are members of the Marantaceae family. The plants are very similar in appearance and cared for in the same way.
The Maranta Leuconeura plant is the plant appropriately called the “Prayer Plant.” The nickname is often applied to Calathea because, like its cousin, this plant also raises and closes its leaves at night and opens them again in the daylight.
This phenomenon is part of the circadian rhythm of the entire family of plants. This action is known as nyctinasty, and is caused by changes in water pressure in the nodes (pulvini) located at the leaf base. These movements help these forest-floor dwellers take the greatest advantage of every ray of light.

Calathea and Marantas
Though it is not correctly called “Prayer Plant”, Calathea has its own exotic, descriptive nicknames. Among them are:
- Zebra Plant
- Peacock Plant
- Rattlesnake Plant (Calathea lancifolia)
- Rattle Shaker Plant
It earns these monikers with its flashy, dramatic markings, and in two instances, its very interesting inflorescences.
Most types of Calathea flowers produce few (if any) flowers, and these flowers are quite small. Plants kept indoors almost never produce flowers. There are a couple of exceptions to this rule of thumb, though.
Calathea Crocata (aka Eternal Flame)
This plant grows to be about ten inches high with a spread of one foot. The leaves are about six inches long and one and a half inches wide. They are dark green with a purple underside.
Bright orange, torch-like flower bracts grow on two-inch spikes. Each clump produces several spikes, which die after blooming is complete; however, the dead spikes are quickly replaced by new ones.
These plants are hardy in USDA hardiness zones 10-11, but they do well as greenhouse plants or houseplants. They need consistent warmth, light, humidity, and water.
Although these plants are costly, many gardeners feel the price is well worth the reward of large numbers of tall, bright orange flowers.
Calathea crotalifera (aka Rattle Snake Plant)
This plant is popular both as a landscape plant and an indoor plant. The flowers of this plant look rather like a rattlesnake’s tail, so it is often referred to as the Rattle Shaker plant. [source]
This variety is widely used, and the flowers make interesting and long-lasting additions to floral arrangements. Rattle shaker inflorescences come in white, yellow, green and red.

Aside from these two notably flowering varieties, Calathea’s flashy foliage is its calling card. The leaves are so striking they hardly look real.
They stand away from the center of the plant stiffly and change their positions ever so slightly from dawn to dusk as a way of making the most of available sunlight, warmth, and humidity.
Here are several of the best choices in non-flowering Calathea:
Calathea Rosea Picta Exquisite Beauty
Calathea Roseopicta is also known as Painted Calathea, Rose Painted Prayer Plant. This species is famous for their colored foliage. The plant has large leaves elliptical in shape.
Each glossy leaf is prominently dark green in color with rose-colored midrib.
In between the margin and midrib is an irregular feathered rosy-colored ring. The underside of the leaf is purple in color with short reddish-brown petioles holding each leaf.
In addition to the beautiful foliage, Calathea Roseo Picta plants also produce white and purple flowers. The flowers are so small that they are considered to be less significant compared to the plant foliage.
The beautiful Calathea Roseo Picta is used by interiorscapers and makes an attractive pooted container plant. It can be used indoors and outdoors.
When grown outdoors, landscapers make use of it as a ground cover or en masse for mix planters and mix borders.
The plant’s leaf colors can add a sense of variety to any garden, landscape, or interior.
Calathea Burle Marxii (Stromanthe Amabilis)
Ctenanthe Burle Marxii also known as Stromanthe amabilis and fishbone prayer plant. Discovered by the botanist Linden, the leaves impressed him so much he added the Latin word amabilis, meaning ‘worthy of esteem’ as the species name.
Burle Marxii is named after the Brazilian landscape designer Roberto Burle Marx.
The plant grows into a dense clump. The undersides of the leaves are bright maroon, on top the oblong leaves with dark green to blue-green sit atop broad silver bands. Mass them several together for a dramatic effect.
This is a compact plant that grows to about a foot high. Leaves are green with grayish/green feathering along the mid-rib. These grow well as a ground cover in a tropical setting.
These plants are hardy in USDA zones 8-11 and can be grown in the non-tropical southern US, but may die back during the winter months.
Calathea Concinna Potted
Calathea concinna or Concinna Prayer Plant has a combination of light green and dark green leaves in a palm-like form.
In a year, Calathea concinna blooms white flower repeatedly. An attractive plant to birds, bees and butterflies.
This plant is an excellent groundcover and for indoor use that requires constant water and never let the soil dry out between waterings.
Calathea Lancifolia (aka Calathea Insignis)
This interesting plant sports narrow leaves of deep olive green with a yellow band around wavy edges. The leaves can be as long as one and a half feet.
The plant has a spread of two feet. Flowers are inconsequential or non-existent. This plant is hardy in USDA zones 9-11.
If you love foliage plants but cannot afford collector’s plants, Calathea Corona may answer to your needs.
Corona is grown its stunning patterned foliage. The shiny leaves are generally olive green in color with dark green edges. Bright silvery gray highlights the center of each leaf.
Each round leaf is generally broad in size and taper to a point. Young or new leaves are usually curled and as they emerge they show off their purplish red undersides.
Like other “prayer plants” the leaves fold at night appearing like hands clasped in prayer. Calathea Corona does well as a potted specimen plant.
Because of its dense foliage, it has this mysterious effect as it conceals its stems when put indoors to accentuate any spot it occupies.
Calathea Makoyana (aka Peacock Plant) is a Brazilian native.
Its leaves are olive green and cream speckled on top and splotchy pink on the underside. The topsides of the leaves are also marked with silver feathering along the veins. This appears as cream colored feathering on the underside.
All-in-all the plant’s appearance is quite flashy! It can attain a height of one or two feet and a width of about a foot. It is hardy in USDA zones 10-11.

One of the beautiful plants you can find in nurseries and garden centers during the spring and early summer is Calathea rotundifolia.
The calathea name came from the Greek word kalathos which means basket; while rotundifolia means rounded leaf.
From the name of the plant itself, you will easily know that calathea rotundifolia is a stocky plant with large and round leaves.
Each leathery-textured leaf is veined with light green and generally shows alternating bronze-green bands.
Calathea rotundifolia is usually grown for its foliage. Because of its short or stocky form, rotundifolia makes a suitable indoor plant as well as a container plant.
Outdoors, rotundifolia should be grown under semi-shade or indirect sunlight.
Calathea Majestica (aka Calathea Ornata)
Calathea ornata (pinstripe Calathea) is a sturdy plant and can grow to a height of six feet and a width of three feet. The leaves are deep green with a reddish/purple underside. They can grow to a length of two or three feet.
The growth process is interesting in that the beautiful leaves start out with pink striping between the veins, which transitions to white striping. This plant is hardy in USDA zones TS 10-11.
Calathea Zebrina (aka Zebra Plant)
Beautiful Zebrina can attain a height of 1-3 feet and a width of one or two feet.
The leaves of this houseplant are velvety green and have alternating bars of olive green and pale yellow radiating from the mid-rib on the topside. The undersides of the leaves are reddish/purple. This plant is hardy in USDA zones TS 10-11.

How To Care For A Calathea Plant
The care for a Calathea can be challenging and not usually recommended for inexperienced gardeners or those seeking easy low maintenance houseplants.
Consistency is the key to Calathea care. You must be prepared to provide consistent warmth, humidity, bright indirect light, and moisture.
Calathea needs protection from both direct sunlight and excessive darkness. The best setting is one with good, bright, indirect sunlight.
These plants can do well in a north facing window. In other settings, be sure to shield the plant against the direct rays of the sun.
Place them in a bright room, but prefer not to be right next to the window. These plants can do well with fluorescent lighting or grow lights.
Consistent Moisture Is Ideal
To keep the soil moisture consistent, it’s a good idea to consider self-watering containers for Calathea and Maranta. Not only do they need consistent moisture but never become waterlogged.
If you hand-water, provide small drinks, with frequent watering throughout the growing season. As soon as the surface of the potting soil begins to dry, you should water. During cooler months, cut back on watering a bit.
Provide Consistent Humidity
High humidity will keep Calathea plants healthy and happy. In fact, lack of humidity is one of the main reasons for lack of success. Misting can help but is not enough on its own.
Plants requiring high humidity often do well in the kitchen or the bathroom since these rooms are naturally more humid than most rooms in the average house. [source]
For large plants, set up a pebble tray with water beneath your containers to provide consistent humidity. Small plants can be successfully kept in a terrarium or bottle garden.
Alternately, you may wish to use a cloche to help retain humidity. This is a glass, bell-shaped covering especially designed to be placed over a plant to maintain high humidity levels.
Remember that indoor humidity levels in winter are very low. This is especially true in homes with central heating.
Providing enough humidity during the winter months can be a real challenge in the average household. It is wise to use a humidifier for the health of your plants and yourself.
During the growing season fertilize once every two weeks with a half-strength mixture of standard liquid houseplant fertilizer. Don’t fertilize at all during the winter months.
Maintain A Consistent Temperature
Calathea like warm temperatures with moderate ventilation. They do not like a lot of air movement or strong drafts. Temperatures should be between 60-70 degrees Fahrenheit during the day and no lower than 50 at night.
How Often Should You Repot Calathea?
Healthy plants can be repotted annually or semi-annually during the spring and summer months. Be sure to repot using new potting soil. Repotting time is the perfect time to propagate plants by dividing them and replanting them.
This is a great way to get more plants to enjoy and share; however, keep in mind that your new young plants will not be as bushy and lush as your old plants.
Calathea grows fairly quickly, so young plants should fill out and look attractive in a short period of time.
How To Propagate Calathea
Division is the best and easiest way to grow more Calathea. You can divide plants in half or in several pieces depending on the size of the original plant.
Just plant each section into its own pot or container. Protect the divisions by keeping them is a warm, shady place. Keep them moist by covering them lightly with plastic.
When you see new growth starting, remove the plastic and begin treating the divisions as you would mature plants.
Calathea Plant Grooming
As with all plants, trim off straggly, damaged or diseased leaves on a regular basis. Dust the plant lightly from time-to-time, and provide more thorough leaf cleaning as needed.
Don’t use leaf shine products at all. To keep the leaves clean, just wipe them off with a damp paper towel or soft, damp cloth. Occasionally, give your plant a gentle shower with lukewarm water. Finish up by wiping the leaves dry with a soft cloth.
Are Calathea Plants Poisonous?
According to the American Society for the Prevention of Cruelty to Animals (ASPCA) Calathea is non-toxic to cats, dogs, horses, and people. [source]

Calathea Plant Problems
As with all plants, when you provide optimum, consistent care you should not encounter too many problems. Most Calathea challenges are caused by too much or too little water or light and/or improper ventilation and temperature control. Here are several of the most common maladies.
What to do about poor growth and brown leaf edges:
If your plant is growing poorly and the leaves have a crispy brown edging, lack of humidity is usually the issue.
Remember these tropical plants need constant warmth and humidity to thrive. Without it, the leaves will just look raggedy. To treat this problem, trim the brown edges off carefully and improve warmth and humidity levels.
What to do about spotted curling leaves and lower yellow leaves:
When the leaves are spotty, curling and yellowed, it means you are not watering enough. Remember to keep the potting soil uniformly moist for the entire growing season. Repotting into a self-watering container can help tremendously with this problem.
What to do about droopy leaves and rotten, limp stems:
When there are signs of fungus and rotting, it may mean that you are watering too much. Again, a self-watering container can help with this.
It may also mean that your plant is too cold or experiencing too much air movement or cold drafts. Move your plant to a sheltered, warm setting away from drafts.
What to do about washed out, faded leaves:
Poor leaf coloration can occur because of improper lighting. Either too much or too little light will cause loss of color and pattern.
Most of the time, exposure to direct sunlight is the problem. Evaluate your lighting situation and make corrections so that your plant receives bright, indirect light and no direct sunlight.
What to do about gray mold (Botrytis):
Sometimes you can go overboard with the humidity levels. If you keep your plant in a very muggy atmosphere, the result can be a mold attack.
If you see spots of gray mold on your plants, trim back the affected area and provide some gentle ventilation.
Place a small fan set on low near your plants. Don’t put the breeze directly on them. Set up your fan so that it provides gentle circulation for the entire area.
Why Is My Calathea Sticky?
If you notice your Calathea has sticky leaves often under the leaves your plant may have plant scale insects. Learn more about this problem of Calathea sticky leaves and how to fix it.
