Pinstripe Calathea
Calathea ornata
Calathea ornata features large, elliptical, dark green leaves adorned with distinct, fine pink or white pinstripes running parallel from the midrib to the margins. The undersides of the leaves typically display a deep purple or maroon coloration.
- Light
- Bright, indirect light for 6 to 8 hours daily. Direct sunlight must be avoided as it will scorch and fade the distinctive leaf markings.
- Water
- Water thoroughly when the top inch of soil feels slightly dry. Use filtered water or rainwater, as the plant is sensitive to chemical additives like fluoride and chlorine found in tap water.
- Growth
- Clumping perennial herbaceous houseplant with an upright to spreading growth habit, reaching mature indoor heights and spreads of approximately 1 to 2 feet with a moderate growth rate.
Care instructions
Provide bright, indirect sunlight and keep the soil consistently moist but never waterlogged. High ambient humidity is essential for maintaining vibrant foliage and preventing crisp leaf edges.
Growing details
Sunlight
Bright, indirect light for 6 to 8 hours daily. Direct sunlight must be avoided as it will scorch and fade the distinctive leaf markings.
Watering
Water thoroughly when the top inch of soil feels slightly dry. Use filtered water or rainwater, as the plant is sensitive to chemical additives like fluoride and chlorine found in tap water.
Soil
Rich, well-draining potting mix with high organic matter, ideally peat-based, maintaining a slightly acidic to neutral pH range of 6.0 to 6.5.
Hardiness zone
USDA hardiness zones 10 to 12. Grown primarily as an indoor houseplant in cooler temperate climates due to its low frost tolerance.
Growth habit
Clumping perennial herbaceous houseplant with an upright to spreading growth habit, reaching mature indoor heights and spreads of approximately 1 to 2 feet with a moderate growth rate.
Bloom season
Rarely blooms when grown indoors. When flowering occurs outdoors, it produces small, insignificant white or purple-tinted flowers clustered on short spikes.
Propagation
Propagated primarily through root division during the spring repotting season. Ensure each division contains a healthy section of roots and several viable stems with leaves.
Common pests & issues
Susceptible to spider mites and mealybugs, particularly in low humidity environments. Leaf tip browning and crisping typically indicate insufficient humidity or sensitivity to tap water minerals.
Similar species
Calathea roseopicta, which features broader oval leaves with circular banding patterns instead of fine parallel pinstripes.
