T he Tricolor Prayer Plant, botanically known as Stromanthe sanguinea 'Triostar', is one of the world's most popular non-toxic houseplants, admired for its colorful variegated foliage and graceful clumping growth habit. Its long, lance-shaped leaves combine shades of vibrant green, creamy white, and pink, with rich burgundy to purple undersides that become especially noticeable as the leaves move throughout the day.
Native to Brazil, it has other common names such as Triostar Stromanthe or Tricolor Stromanthe.
It belongs to the Marantaceae family, commonly called the prayer plant family, and its leaves naturally rise and fold upward at night in response to changing light conditions, a fascinating movement known as nyctinasty.
This moderate-growing evergreen typically reaches 3 feet tall and about 2 feet wide indoors, making it an excellent choice for living rooms, offices, bedrooms, and other indoor spaces where its colorful foliage can create a striking accent without taking up excessive floor space.
Its pet-safe nature and tropical appearance have also made it a popular choice for plant lovers who want a colorful houseplant that is safe to keep around cats and dogs.
During spring and summer, mature Stromanthe plants may occasionally produce clusters of red to pink bracts surrounding small tubular flowers, although flowering is uncommon indoors and the plant is grown primarily for its spectacular variegated foliage rather than its blooms.
When and How to Water Your Triostar Stromanthe
It prefers consistently moist soil but never waterlogged, as its root system appreciates hydration without being oversaturated. Rather than letting the soil dry out completely or keeping it soaking wet, allow the top 1–2 inches of the potting mix to dry out slightly between waterings. Avoid overwatering or leaving the pot sitting in standing water, as soggy soil can quickly lead to root rot and fungal issues due to its relatively sensitive root system.
The triostar plant should typically be watered every 1–2 weeks during the active growing season (March–September) and every 2–3 weeks during the dormant winter season (October–February), adjusting as needed based on your indoor humidity, temperature, pot type, and soil dryness.
During the spring and summer, water your plant when the top 1–2 inches of the potting mix feels dry to the touch. Water thoroughly with room-temperature filtered or distilled water until excess water drains from the bottom of the pot, then empty the saucer so the roots are not left sitting in water.
During the fall and winter, reduce watering because the plant grows more slowly and the soil takes longer to dry. Allow the top portion of the potting mix to dry out before watering again, and avoid keeping the soil wet for extended periods to help prevent root rot.
Light Requirements – Where to Place Your Tricolor Prayer Plant
When growing indoors, plant your prayer plant in bright, indirect light for 6–8 hours each day to encourage healthy growth and vivid pink patterns.
A spot near an east-facing window or a few feet away from a bright south- or west-facing window is ideal. Avoid direct afternoon sun, as it can fade the rich variegation and scorch the leaves.
When grown outdoors, it performs best in partial shade to deep filtered shade in USDA Hardiness Zones 10–11, where temperatures remain above 60°F year-round.
Place it on a covered patio, shaded porch, or beneath a tree canopy where it is protected from direct sunlight. In cooler regions, grow it in a container and bring it indoors before temperatures fall below 55°F.
The vibrant pink and cream leaf coloration develops best in bright, indirect light. Insufficient light can cause slower growth, duller leaves, and less pronounced striping, while direct sunlight may scorch the foliage and burn its distinctive markings. When provided with proper growing conditions, the Tricolor prayer plant remains attractive throughout the year and provides dramatic foliage contrast compared to many traditional green houseplants.
Optimal Soil & Fertilizer Needs
The Stromanthe triostar grows best in a loose, chunky, well-draining potting mix that retains moisture while allowing both air and excess water to flow freely around the roots. Planting them in ordinary heavy garden soil will result in compacted roots, stunted growth, and most likely root rot. Instead, make or buy a well-draining potting mix, or ideally use our specialized potting mix that contains 5 natural substrates and mycorrhizae to promote the development of a strong root system that helps your houseplant to thrive.
To support healthy foliage and vibrant pink patterns, feed your plant with a balanced liquid NPK fertilizer during the spring and summer growing season. Apply fertilizer at half-strength every 4–6 weeks. Reduce or stop fertilizing during fall and winter when growth naturally slows, and the plant requires fewer nutrients.
How to Grow Indoors as a Houseplant
The tricolor Stromanthe makes a stunning, easy-to-care-for houseplant, admired for its waxy, multicolored foliage and upright habit that brings bold tropical color to indoor spaces.
- Place your plant in a spot that receives bright, indirect light, such as right next to an east-facing window or a few feet away from a bright south-facing window.
- Intense, direct afternoon sun must be avoided to prevent the harsh rays from scorching and fading the vibrant pink and green foliage.
- This tropical native should only be watered when the top 1–2 inches of the potting mix feels dry to the touch.
- All excess water needs to drain freely from the bottom of the pot so the roots never sit in waterlogged soil.
- The Tricolor prayer plant must be kept in a warm room far away from drafty doorways, air conditioners, and heating vents to avoid sudden temperature shocks and dry air.
Hardiness Zone & More
In the United States, this Triostar Stromanthe is most commonly grown as an indoor houseplant.
Outdoors, it can be grown year-round only in frost-free regions such as southern Florida, Hawaii, and Puerto Rico within USDA Hardiness Zones 10–11.
It performs best in bright shade or filtered light, making it an excellent choice for covered patios, shaded courtyards, and protected tropical garden beds.
It thrives in warm temperatures between 65°F and 80°F and should be protected from temperatures below 55°F. It also prefers moderate to high humidity levels of 50% or greater, which help keep the foliage lush and support broad leaf expansion without crisping edges. Good air circulation is beneficial, but the plant should be shielded from strong winds and drying drafts that can snap its foliage.
Wildlife – Stromanthe tricolor Flowers Attract the Following Friendly Pollinators
This tricolor plant is grown primarily for its colorful, unique foliage rather than its value as a pollinator plant. However, when grown outdoors in tropical or subtropical climates, its small tubular flowers, which produce nectar, may occasionally attract butterflies, curious honeybees, beneficial beetles, and various small pollinating insects that cruise the garden understory.
According to the ASPCA, the question is Stromanthe triostar is 100% non-toxic and completely safe for cats, dogs, and humans if accidentally touched or ingested. It contains no harmful sap or saponins, making it an ideal choice to style safely on table tops, plant stands, or floor displays around curious pets and children.
How to Propagate Your Triostar Stromanthe
This plant can be easily propagated through division taken during the warm spring or early summer months during repotting.
- Locate a healthy, mature plant with multiple root clumps.
- Gently separate a section of the root ball containing 2–3 healthy leaves and stems using a sterile blade or your hands.
- Insert the rooted division directly into moist, lightweight soil or propagation mix.
- Keep the new plant in a warm, highly humid spot with bright indirect light.
- Over several weeks, it will establish its new root system and transition into a full standalone houseplant.
Potting and Repotting Your Plant
This decorative houseplant prefers being relatively cozy in its container and has a fibrous root system that doesn't require massive amounts of space. Repot your tricolor plant only every 1–2 years during the spring, or whenever you notice the roots crowding the surface, winding tightly around the bottom of the pot, or pushing the soil mix out of the container.
Always choose a container with excellent drainage holes at the bottom; plastic grower pots or porous unglazed pots are highly recommended to help excess moisture drain evenly. Move up only one pot size at a time (for example, from a 4-inch grower pot to a 6-inch pot) to prevent excess surrounding soil from holding onto too much water. When you finish repotting, use a loose, moisture-retentive organic mix and water gently to settle the soil around the roots.
