‘Triostar’

Stromanthe ‘Triostar’, Stromanthe thalia ‘Triostar’, is a tropical member of the prayer plant family grown for its dramatic multicolored foliage. Its long leaves are irregularly patterned in green, cream and pink, with deep pink to burgundy coloring underneath. No two leaves develop exactly the same pattern, and new foliage can emerge tightly rolled before opening to reveal its final mix of color. Like Maranta and Calathea, Stromanthe naturally moves its leaves throughout the day, often lifting them higher in the evening and showing off those colorful undersides.

Triostar grows as an upright clump rather than a vine or climbing plant. New shoots emerge from underground rhizomes, which are horizontal stems beneath the soil, allowing an established plant to gradually become wider and fuller. It does not need a pole or vertical support. Indoors, it can develop into a fairly substantial floor or tabletop plant over time, with long leaves held on upright stems above the pot.

For natural light, start Triostar approximately 1–3 feet from an east-facing window or 1–3 feet from a north-facing window. Stromanthe Triostar prefers approximately 400–800 foot-candles at the leaves. Foot-candles simply tell you how much light is actually reaching your plant. Its cream and pink portions contain less chlorophyll than the green tissue, so useful light is important for supporting the plant, but stronger light is not automatically better. Window direction and distance are starting points. Trees, overhangs, neighboring buildings, window size, season, screens and glass can all change how much light actually reaches the foliage.

If you’re using grow lights, choose a 5000–6500K light and aim for the same approximately 400–800 foot-candles at the foliage. Kelvin tells you the color of the light, not its strength. Foot-candles tell you how much light is actually reaching the plant. There is no universal distance between Triostar and a grow light because fixtures produce very different amounts of light. Measure at the leaves and adjust based on what is actually reaching the canopy.

Water when your plant needs watered. Triostar generally prefers a more even moisture cycle and should not be taken through the substantial dryback we would use for many succulents or thicker-leaved plants. Let it use some of the available moisture before thoroughly watering again, while avoiding both prolonged dryness and a root zone that remains continuously saturated. Use an airy, well-draining mix that can retain some moisture while still allowing oxygen around the roots. Water quality and fertilizer salt buildup are also worth considering if browned or crispy margins become a repeated pattern.

Read the leaves, but remember that their daily movement is normal. Leaves lifting, lowering and occasionally changing their angle considerably between day and night aren’t automatically asking for water. Leaves that remain tightly curled, repeatedly develop crispy margins or lose firmness are reasons to check the root zone and overall environment. Stromanthe also prefers a warm, relatively stable environment, so cold drafts and abrupt environmental changes can show up in the foliage.

Success looks like sturdy upright growth, new shoots emerging from the base and leaves continuing to open with strong green, cream and pink patterning. As the rhizomes spread, the plant should gradually become a fuller clump rather than simply growing taller. An older leaf developing an imperfect edge doesn’t mean the entire plant is unhappy. Watch the newest growth. When Triostar continues producing substantial, colorful leaves and new shoots from the base, the plant is moving in the right direction.
