How to Grow
For outdoor success in zones 10-12, plant your Stromanthe sanguinea ‘Tristar’ in fertile, moist, yet reliably well-drained soil. Location is crucial; the ideal spot offers light or dappled shade, performing best with gentle morning sun and protection from harsh afternoon heat. Foliage will quickly burn if exposed to direct, intense sun, particularly during hot summer periods.
Watering should be consistent; soils for the Stromanthe must never be allowed to dry out completely, reflecting its native rainforest origins. When grown indoors north of Zone 10, aim for high ambient humidity—consider placing the container atop a bed of moist pebbles or implementing a daily foliage misting. Bring houseplants inside when temperatures begin to dip to 50°F in the fall.
The robust nature of this plant contributes to its low maintenance level, requiring minimal intervention beyond consistent watering and appropriate light management. This attention prevents both desiccation and root/stem rot, which are key issues to monitor. Ensure containers have excellent drainage to support the needs of the Stromanthe sanguinea ‘Tristar’.
Landscape Uses
The visual impact of the variegated Stromanthe makes it perfect for enhancing shaded patio settings where its color can truly pop against dark greens and browns. It excels in borders or nestled within tropical understories where the light is filtered and gentle, complementing ferns and other broadleaf shade lovers.
When grown as a houseplant, the Stromanthe offers a vertical element perfect for brightly lit corners or eastern-facing windows indoors. Its compact nature when potted allows it to serve as living décor on tabletops or stands, bringing the dramatic foliage of the rainforest environment indoors.

Noteworthy Characteristics
Stromanthe sanguinea, commonly called stromanthe, is an upright rhizomatous perennial that typically grows to 5’ tall and 3’ wide outdoors but to a more modest 2-3’ tall when grown indoors as a houseplant. It is native to rainforests in Brazil. Lanceolate to elliptic-oblong, dark olive green leaves (to 20” long and 6” wide) have red undersides. Leaves appear in a basal clump and along branching stems. This is a prayer plant family member whose leaves fold together at night in a manner reminiscent of praying hands. Leaf folding has the added attraction of showing off the red leaf undersides. Tiny white flowers with orange-red sepals and showy cherry-red bracts bloom in panicles in winter and spring. The cultivar ‘Tristar’ is particularly popular, featuring showy olive green leaves variegated with white, cream and pink.
Tolerances
Potential Problems
The primary adversaries for healthy Stromanthe growth are common houseplant pests and moisture-related disorders. Mealybugs and spider mites may occasionally plague indoor specimens, especially when humidity levels drop too low. Regular inspection of the leaf undersides is necessary to catch infestations early.
Overwatering is perhaps the most significant risk, quickly leading to root or stem rot, especially if soil drainage is poor. To prevent this, ensure the soil is always kept moist but never saturated, balancing the plant’s need for consistent hydration with adequate aeration. Good horticultural practices when caring for Stromanthe sanguinea ‘Tristar’ will mitigate most issues.

Conclusion
The ‘Tristar’ cultivar presents an unmatched tropical aesthetic through its stunning, multicolored, variegated leaves and fascinating nocturnal leaf movements. Its low maintenance requirements make the Stromanthe sanguinea ‘Tristar’ an excellent choice for both dedicated indoor gardeners and landscape designers in warm climates. Before planting, confirm that your local climate aligns with USDA Zones 10–12, or prepare to grow this magnificent Stromanthe indoors.
Companion Planting
When selecting neighbors for your Stromanthe, selection should focus on plants sharing similar requirements for high humidity and consistent moisture under part shade conditions. Consider pairing the bright variegation of the ‘Tristar’ with deep green foliage plants that thrive in dappled light. Excellent companions might include Calatheas, ferns like the Boston Fern (Nephrolepis exaltata), or other shade-loving Marantaceae members that appreciate similar soil fertility.
These companions should also share the medium water needs of the Stromanthe, ensuring that a single, consistent watering schedule can keep all plants happy. Avoid drought-tolerant xeriscaping favorites, as the need to keep Stromanthe soil from drying out will be detrimental to low-water companions.
Propagation Tips
The most reliable method for multiplying Stromanthe sanguinea ‘Tristar’ is through division of its underlying rhizomes. This is best performed when repotting or dividing the plant, ideally in the spring as new growth begins to emerge. Carefully lift the plant and gently tease apart sections of the rhizome clump, ensuring each new division has at least two or three healthy stems and an adequate network of roots attached.
Once divided, immediately plant the new sections at the same soil depth they occupied previously. Keep the newly potted divisions consistently moist and placed in a warm area with bright, indirect light until new root establishment is confirmed. Division ensures that the new plants are exact genetic replicas of the parent, maintaining the prized variegation of the Stromanthe cultivar.
