About Ctenanthe
A stunning prayer plant relative with elongated, silvery-green leaves marked by dark green herringbone patterns and rich purple undersides. Like its Calathea and Maranta cousins, its leaves fold upward at night in a prayer-like motion. It forms dense, bushy clumps that add a tropical, lush feel to shaded indoor spaces in Filipino homes. Ctenanthe belongs to the Marantaceae family and originates from Brazil (tropical rainforests); cultivated as an ornamental houseplant worldwide..
Ctenanthe is gaining popularity among Filipino indoor plant enthusiasts who love the prayer plant family but want something slightly easier than Calathea. The 'Grey Star' variety is especially popular on Shopee and Lazada plant shops. Manila's high humidity gives it a natural advantage over growing conditions in temperate countries. Prices range from PHP 200-600 depending on size and variety. It pairs beautifully with Calatheas and Marantas for a lush, tropical indoor jungle look that is very on-trend in Filipino plant circles.
Also known as: Prayer Plant.

Propagation Steps
- Step 1: Remove the plant from its pot and gently separate the root ball into sections.
- Step 2: Ensure each division has at least 3-4 stems with healthy roots attached.
- Step 3: Trim any damaged roots or yellowed leaves from each division.
- Step 4: Pot each division in fresh, peat-based potting mix and water thoroughly.
- Step 5: Keep in warm, humid shade for 2-3 weeks while the divisions recover and establish.
Care Guide
Sunlight
Medium to bright indirect light; no direct sun, which causes leaf curling and fading. Position your ctenanthe where it receives the right amount of light for healthy growth in Philippine conditions.
Water
Keep soil consistently moist but never waterlogged. Water 2-3 times per week, using room-temperature water. Sensitive to chlorine — let tap water sit overnight before using. Adjust frequency during the Philippine rainy season when humidity is higher and soil stays moist longer.
Temperature & Humidity
Ideal temperature range: 22-30°C (thrives in Metro Manila warmth; avoid temperatures below 18°C and cold AC drafts). High — 60-80%. Manila's humidity suits it well; mist daily in air-conditioned rooms or place on a pebble tray with water. The warm, humid Philippine climate is well-suited for growing ctenanthe outdoors or indoors.
Fertilizer
Balanced liquid fertilizer (10-10-10) at half strength every 2-3 weeks during the growing season (May-October).
Pruning
Remove brown or damaged leaves at the base. Thin out overcrowded clumps to improve air circulation.
Toxicity & Safety
Non-toxic to humans and pets. Safe for homes with children, cats, and dogs.
Common Problems & Solutions
Brown, crispy leaf edges
Cause: Low humidity, underwatering, or chlorinated tap water
Solution: Increase humidity with a pebble tray or humidifier. Use filtered or dechlorinated water.
Curling or folding leaves during the day
Cause: Too much direct light or underwatering
Solution: Move to a shadier location. Water more consistently — soil should stay evenly moist.
Spider mites (fine webbing on leaf undersides)
Cause: Dry air, especially in air-conditioned rooms
Solution: Mist leaves frequently. Wipe both sides with a damp cloth. Spray with neem oil weekly until mites are gone.
Faded leaf patterns
Cause: Too much direct sun bleaching the colors
Solution: Move to filtered or indirect light. The silvery markings and purple undersides are most vivid in medium light.
