Where Does The Triostar Stromanthe Come From?

The Stromanthe Triostar goes by many names, from the Stromanthe Sanguinea, Triostar Stromanthe, Magenta Triostar to just the Triostar. The tropical perennial comes from the rainforest and Brazilian jungle.

One thing that’s very noticeable in this plant is the full variegated foliage with tins of pink. You can grow the plant outside in humid and hot climates, and it does well indoors

While the plant can develop flowers in spring outdoors, the main attraction is the colorful leaves. Your plant is a fast grower but can become a bit temperamental. It slows down when the roots are bound, do not receive enough light, or are always disturbed.

However, if you live in zones 10 to 12 (USDA), you can easily grow your plant.

Stromanthe Triostar Care Basics

Stromanthe Triostar Plant

The short and sweet answer is that your Magenta Triostar needs bright indirect light with the soil moist and well-drained. Furthermore, the temperature and humidity also play a big part in this plant’s survival.

Best Potting Mix

To prevent your Triostar Stromanthe from throwing a fit, provide well-draining soil that helps retain some of the moisture. You can go for a perlite-based potting mix with soil pH levels between 6 to 8. The water needs to drain freely, and adding a peat base with an equal part of perlite added helps.

Watering Needs

Now, gardeners, this is where you need to be strict. Appropriate water volume is vital for Triostar Stromanthe to survive. If you get this wrong, your plant will be finicky and start looking unhealthy. Do not waterlog the soil but keep it moist. During winter, you can let the plant go a bit drier with only the top inch of soil dry before watering.

To add to its fussiness, tap water is not your best choice. Instead, use distilled water at room temperature.

A sign that your plant is having water concerns is when the leaves turn brown or yellow. This is a symptom of root rot. To check, remove the plant from the pot, rinse the roots, trim off the rotten portions, and transplant to a new pot. You may prevent root rot by allowing the soil to dry out before watering.

Light Requirementplant lighting requirement

If you want to provide the best Triostar plant care, never place it under direct sun. Exposure to direct light causes the leaves to burn. The more indirect light the plant receives, the more variegation it shows. We said this plant is finicky!

You can place it at a spot on the east or a north-facing window. Also, remember to rotate your plant once a week to provide even growth. It can grow in medium levels of indirect light, but the brighter it becomes, the more it grows

Temperature and Humidity Requirement

plant temperature requirementStromanthe Sanguinea triostar needs a temperature between 65° to 80°F (18 to 27°C). It can tolerate temperatures down to 40°F (4°C) but is not recommended. Your Triostars enjoy a humid environment, so avoiding dry conditions help.

So, a warm place with a humid environment helps the foliage look better. You can mist your plant every day to keep the levels of humidity at the desired range. A great place for the plant is in your bathroom or kitchen. You can also invest in a humidifier or a pebble tray, making it a suitable option for home decor.

Another plant care tip is to move your plant away from AC, drafts, or dry heat. Those could lead to physical damages such as the wilting and browning of the leaves.

Fertilizer Requirement

As a rule of thumb, use a balanced liquid fertilizer every two to three weeks in spring or summer. The Triostar Stromanthe sanguinea will love this feeding. We recommend diluting the fertilizer to half strength and never feed it during the winter months. It causes root burn making your exotic plant sick.


Your plant is a slow grower and does not need regular repotting, unlike other plants. If it flowers, count yourself lucky. If not, the colorful foliage makes up for it. You can transplant them when you see the roots growing through the bottom of the vessel. The best time to do this is in spring and summer.

Repot your Stromanthe plants to a pot bigger than the previous container to accommodate the growing root system. Remember the drainage holes are sufficient to keep the potting soil moist but not too wet.


Part of the Triostar care and maintenance is occasional pruning. The only time you need to prune your plants is when the leaves become discolored or damaged. Wait for the growing season to do this management practice.

Remove the leaves from the base using your garden shears. You may also trim minor blemishes on the foliage of your plant.

Plant Propagation

During spring, before the new growth starts, you can separate the rhizomes of your Triostar plants.

Here is the step by step procedures on how to do it:

-Start by removing your plant from its abode and shake off the excess soil gently.

-Separate the rhizomes using your fingers and leave up to three leaves.

-With your garden shears, cut through the connected roots.

-Take the divided plants and place them in separate containers using fresh soil.

-Place your Triostars in a warm area with a high humidity level under bright indirect light. Water the soil with filtered water. You will notice new leaves starting to shoot out once it has grown new roots.
