Triostar stromanthe (Stromanthe sanguinea) is a full-fleshed, variegated plant with vivid shades of pink. Although it can be grown outside in hot and humid environments, it thrives indoors and is most commonly used as a houseplant.

Triostar is a member of the prayer plants family. It folds its leaves at night and can be mistaken for the calathea. While flowers can grow on this plant in spring if it is kept outside, its main attraction indoors or out is its large, vibrant leaves. Although it is a medium-fast growing plant, it can become temperamental and slow down if it feels stressed, root bound or doesn’t get enough sunlight.

Triostar Stromanthe care

This plant is not for beginners. This plant requires a lot of care and nurturing to thrive in the environment it prefers.

Triostars thrive in humid, warm conditions. This is why they are a great houseplant, if placed in a window that receives enough indirect light. The plant should not be placed near an air conditioner or radiator.

A good way to ensure even distribution is to turn the plant once per week. They will grow in the same direction as the sun. You can also mist the plant to give it the humidity it needs.

Triostar Stromanthe should only be cultivated in well-drained, fertile and kept moist.


Light that is similar to what you would find in a rainforest environment is often needed by tropical plants.

Your triostar stromanthe should be placed in an area that receives dappled sunlight to maximize its chances of flourishing. It can cause damage to the leaves if it gets too much sun. Dust the leaves of a houseplant to allow it to receive more sunlight.


A soil that is light, well-drained, breathable and easy to work with is essential for your triostar. It should retain moisture but not be too heavy or claggy.


It is crucial to ensure that your triostar has enough water. If this is not done correctly, the plant could quickly look unhealthy.

It is best to keep the soil moist but not too dry. This plant can be dried a bit if it is exposed to cooler temperatures. Good results are usually achieved by allowing the soil to dry for a few inches before watering again.

The plant can be very picky about water quality and temperature. Tap water is not the best choice as it contains chemicals that can cause allergic reactions. Spring water, however, is also an option. Don’t let the water cool down too much.

If the leaves turn yellow or brown, you will know that it is suffering from watering problems. If your plant’s leaves become brown, you can remove them from their pot and soak them in water for several hours. Then drain, rinse, and repot the plant. If you see yellow leaves, it is likely that the soil has become waterlogged. You will need to dry the soil before watering again. This process may take several weeks and patience is required. If the soil is still wet, it is time to repot your plant.

Temperature and humidity

The triostar, like all tropical plants, prefers warm temperatures and a humid environment. It thrives in temperatures between 65 and 80 degrees Fahrenheit.

Many people keep their triostars in a bathroom window. This allows them to get plenty of humidity. They are not fond of environments with dry heat or air-conditioning.


A balanced, diluted fertilizer can be given to your triostar every two weeks to encourage growth. Root burn can be caused by too strong or frequent fertilizer application.

Organic fertilizers are less strong and may not require diluting.

During winter dormancy, your plant will not need to be fertilized.

Propagating Triostar Stromanthe

Unfortunately, these plants can’t be grown from stem cuts. You can also separate the rhizomes from a healthy mother plant if you want to grow another plant. It is important to ensure that each division has at most three to four leaves attached, that the potting soil used is good quality and moist, and that the work is done in spring or early summer. Make sure you do not start new growth by making the divisions.

Potting and repotting

Triostars are a common houseplant that can be grown in containers. It is important to make sure that the pots are deep enough for the roots to be able to take water, but not too deep so that it sinks and becomes stagnant. To prevent waterlogging, you will need plenty of drainage holes.

It is possible to help your plant thrive by repotting it after a few years. You should watch out for roots that are beginning to grow from the bottom of your container. If you notice this, it is probably time to move them. This is best done in spring.

Common Pests and Diseases

If the humidity is low, common aphids or spider mites may be attracted to the stromanthe tristar plant. This problem can be solved with mild soaps or neem oils sprays. Plants that are too dry can attract mold and fungus. To keep the environment moist, mist the plant every day.
