Strobilanthes dyeriana
The Persian Shield is a showstopper in the world of houseplants, adored for its breathtaking iridescent foliage. Native to the humid tropical forests of Myanmar, its lance-shaped leaves shimmer with a metallic, neon-purple hue and silver sheen, contrasted by deep green veins and maroon undersides. This royal-looking plant adds an exotic splash of color that outshines most flowering plants.

This plant is generally considered non-toxic to dogs and cats. However, the sap may cause mild skin irritation in sensitive individuals, so it is best to wear gloves when pruning.
Care Guide
Lighting and Color Persistence
To maintain its vibrant violet color, place the Persian Shield in bright, indirect light. While it can tolerate lower light, the metallic purple will fade to a dull green. Avoid direct afternoon sun, which can scorch the delicate foliage.
Watering Essentials
This plant is quite dramatic and will wilt visibly if thirsty. Keep the soil consistently moist but never waterlogged. Water when the top 0.5 to 1 inch of soil feels dry. Using lukewarm water is recommended to prevent root shock.
Humidity and Warmth
As a tropical native, it requires high humidity (above 50%). Use a humidifier or a pebble tray to prevent crispy leaf edges. It thrives in temperatures between 65°F and 75°F (18°C-24°C) and should be protected from cold drafts below 60°F.
Pruning and Longevity
Persian Shields can become leggy over time. Pinch back the tips of the stems to encourage a bushier growth habit. Because these plants tend to lose their vigor after 2-3 years, it is common practice to propagate stem cuttings regularly to start fresh, vibrant plants.
Seasonal Care
During winter, the plant's growth slows. Reduce watering and stop fertilizing, but maintain high humidity as indoor heating often dries out the air.
