Persian Shield
Strobilanthes dyerianus
Iridescent silver-purple foliage that shimmers like a jewel — one of the most visually striking tropicals you can grow.
Overview
Persian Shield is one of the most visually spectacular houseplants available. Its leaves display a stunning iridescent silver-purple sheen that shifts in different lighting — almost metallic in appearance. Native to Myanmar, it's a fast grower that responds well to regular pinching. The color is most intense in bright indirect light, making placement important for getting the best display.

Soil
Rich, well-draining potting mix
Temperature
60–85°F (16–29°C)
Fertilizer
Balanced fertilizer every 2–4 weeks during spring and summer
Detailed Care Guide
Light
- Needs bright indirect light to maintain its metallic silver-purple sheen
- More light = more intense iridescent color — this is a light-hungry plant
- Some direct morning sun (1–2 hours) is beneficial
- Avoid harsh afternoon direct sun which can scorch leaves
Watering
- Water every 5–7 days — allow the top inch of soil to dry between waterings
- More drought-tolerant than it looks; slightly underwatering is better than overwatering
- Ensure the pot has drainage holes — soggy soil causes root rot
- Reduce watering in winter when growth slows
Soil
- Use a rich, well-draining potting mix — standard indoor potting soil works well
- Add 20% perlite for improved drainage
- Repot in spring when roots become crowded
- Slightly acidic soil (pH 5.5–6.5) is ideal
Temperature & Humidity
- Prefers 60–85°F (16–29°C) — avoid cold drafts and temperatures below 55°F
- Moderate to high humidity (50–70%) enhances leaf color and prevents crispy edges
- Mist occasionally or use a pebble tray
- Keep away from cold windowsills in winter
Difficulty Level
Beginner — Persian Shield is easy to grow and very rewarding. The main requirement is bright indirect light for the best color. Regular pinching keeps it bushy and full.
Extra Notes
Pet safe — completely non-toxic to cats, dogs, and humans. Persian Shield is one of the most photographed houseplants because of its extraordinary iridescent color. Pinch tips regularly — this encourages branching and keeps the plant full rather than leggy.
Pro Tip
Pinch the growing tips every few weeks to keep Persian Shield bushy. The pinched cuttings root easily in water — you'll have new plants to share within a month.

Just Received This Plant?
If you just received a cutting or node: place in a glass of water in a warm, bright spot out of direct sun. The iridescent color may look dull at first — this is normal stress. Roots appear in 2–3 weeks. Once rooted, pot into rich well-draining soil and keep humidity above 50%. Avoid cold windowsills — this plant hates cold.
If you just received a potted plant: unbox and place in bright indirect light immediately — Persian Shield needs light to maintain its color. Water if the soil is dry. Expect some leaf drop or color dulling in the first week as it adjusts — this is normal. Keep humidity above 50%. Do not fertilize for 4–6 weeks. Pinch any leggy stems to encourage bushy new growth once the plant has settled in.
Basic Care Instructions
Place in bright indirect light for the most intense color, water every 5–7 days allowing the top inch to dry, and maintain moderate to high humidity. Fertilize every 2–4 weeks in spring and summer. Pinch tips regularly for bushy growth.
Propagation
Stem tip cuttings root in water or moist soil in 2–3 weeks. Take 4-inch cuttings, remove lower leaves, and keep warm and humid while rooting.
