The complete variegate foliage of the triostar stromanthe (Stromanthe sanguinea) is striking, with vibrant pink colors. It may be grown outside in hot, humid conditions, but it thrives indoors and is more usually used as a house plant.

To appear its best, Stromanthe Triostar, a Calathea cousin, requires the humid conditions and heavily filtered light of a rainforest understory. Let’s take a look at what they have to offer before we talk about the terms of your peonage to their enthralling foliage.

Stromanthe is a genus of plants belonging to the marantaceae family. Calathea is a separate genus that belongs to the marantaceae family. Stromanthe and calathea are closely related, sharing many characteristics and having a similar appearance. Because many plants in the Marantaceae family fold up their leaves at night, as if in prayer, they are popularly referred to as the prayer plant family.

This is not a plant for inexperienced gardeners. It needs a great deal of care and caring in order for it to keep in the precise habitat in which it like to dwell.

Calathea Triostars thrive in warm, humid environments, which is why they make an excellent houseplant when placed in a window with enough indirect light. However, keep the plant away from radiators and air conditioners.

Because the leaves will grow in the direction of the light, turning the plant around once a week can assist guarantee a healthy, uniform distribution. Misting can also aid in the creation of the necessary humidity.

Triostar stromanthe should be potted in healthy, well-drained soil that is kept moist but not wet.


Calathea Triostars interact with sunlight in a unique way. The best lighting is medium filtered light because the plant can’t stand direct sun and burns rapidly.

Their optimum location is generally near an east-facing window that gets enough of morning sun, and they should be no more than four feet away from the window. Another acceptable option is a sunny northern exposure.

The strange behavior of Stromanthes with light, which can be perplexing to its owners. Most variegated plants lose their color in low light, so placing the plant in bright light sounds logical—but the Triostar is an exception and may not respond well.

To comprehend their requirements, we must study how they survive in the wild. The strong, fierce sun that pours down on the top levels of a rainforest is deflected by heavy tree foliage, making light scarce on the ground where they live—but the same sun may scorch sensitive leaves with dappled rays that break through. The Triostar copes by shifting its position.

The red-shaded undersides of the leaves save light by absorbing rays at faster rates, giving them a strange pinkish glow. In the dim light of dark and night, the leaves fold up, then open and turn their reflective white-streaked side to the sun each morning. The photoactive leaves move swiftly (for a plant) throughout the day to follow the light, revealing either their reflective surface or protective coating as the light changes.

Because of these adaptations, the Triostar can maintain its variegation in lesser light than many other species. They also make it difficult to predict the plant’s behavior. The greatest suggestion is to keep an eye on the plant’s health and be ready to make changes as needed.

A well-draining, airy, and light soil is required for your triostar. It should not be overly thick or claggy, despite the fact that it must retain moisture.


It’s critical to make sure your triostar receives enough water on a regular basis. If you get this wrong, the plant will rapidly become sick.

It is preferable to keep the soil moist but not waterlogged. This plant can be maintained a little drier in cooler weather. Allowing only the top inch of soil to dry before rewatering is generally sufficient.

This plant can be picky about the water’s quality and temperature. Because the plant is sensitive to the toxins in common water, tap water does not offer the best results. Although distilled water is preferred, spring water can suffice. Also, make sure the water isn’t too cold.

When the plant’s leaves become brown or yellow, you’ll know you’re experiencing watering problems. Remove the plant from its pot and place it in a dish of water for a few hours before draining, cleaning, and repotting if the leaves turn brown. Yellow leaves indicate that the soil is wet and needs to dry off before being watered again. You’ll need patience for this procedure, since it might take many weeks. It’s time to repot the plant if the soil won’t dry out.

Humidity and Temperature

The triostar enjoys a humid habitat with warm temperatures, as one would anticipate from a tropical plant species. Temperatures between 65 and 80 degrees Fahrenheit are ideal.

Many individuals keep their triostars in their bathrooms. They’ll receive enough of humidity this way. They dislike hot, dry conditions, as well as air conditioning.

Every few of weeks, feed your triostar a diluted, balanced fertilizer to help it flourish. To avoid root burn, make sure the solution isn’t too harsh or used too frequently.

You may not need to dilute organic fertilizer since it is less potent. During the winter months, when your plant is dormant, you won’t need to fertilize it.

How to Grow and Propagate Triostar Stromanthe

While fresh triostar stromanthe plants cannot be grown from simple cuttings placed in water, two (or more) plants can be obtained from one. Plants of the Triostar stromanthe can be reproduced via division.

It’s ideal to propagate your plant in the spring or summer to enhance your chances of success. A healthy mother plant, fresh soil, a clean, sharp set of pruning scissors, and as many appropriately-sized pots as you want to grow new divisions are all required.

Step 1: Take the mother plant out of its pot. With your fingers, loosen the roots and soil, then carefully pick apart the rhizomes to separate them into a few clumps. At least two or three leaves should be present in each cluster. To separate any attached roots, use your shears or a clean, sharp knife.

Step 2: Fill new pots with fresh soil to accommodate the additional divisions. In the new pots, plant the fresh divisions. In a container with new soil, replant the mother plant. Soak the plants in water until the soil is evenly moist.

Step 3: Keep the young plants in a warm, indirect light environment. Keep sure the soil is moist but not saturated. It’s an indication that the roots have established themselves when fresh leaves sprout.


The only pruning required is to trim any damaged leaves. Using sterilized shears, cut the stem at the base.

Damaged leaves are removed as part of routine maintenance, which they don’t mind. Even thriving plants might have a few leaves that dry up or deteriorate at any time.

Avoid removing more than a third of the foliage at once since this reduces the amount of light reaching the remainder of the plant.


Triostars thrive in pots as ordinary houseplants. All you have to do is make sure the pots are deep enough to allow the roots, but not so deep that the water sinks and stagnates. Water-logging prevention also need a large number of drainage holes.

After a few of years, repotting your plant can help it grow. Grow an eye out for roots growing out of the container’s bottom. It’s probably time to transfer them if you notice this. This is best done in the spring.

Typical Pests and Diseases

If the humidity is too low, the stromanthe triostar plant may attract common aphids and spider mites. That issue can be solved with a light horticultural soap or a neem oil spray. If your plant becomes too dry, fungus and mold will thrive. To keep the plant’s habitat damp, mist it every day.

Misting can create spotting if the water droplets are too large and take too long to dissipate. It might also happen if there are pollutants in the water.

Another cause might be water-repellent dry areas in the soil. After watering, carefully probe the soil to see if it’s dry. Any spots you locate should be broken up and soaked.

Triostar Turning Yellow?

Overwatering is the most common reason, although strange coloring on Triostar leaves is mainly due to their roots. Excess chemicals and salts from fertilizers might be present in the soil. Purified water can be used to flush. Leave the roots alone until the color improves.
