Description
A variegated prayer-plant relative with cream, green, and pink foliage plus rosy undersides. It is gorgeous, but it is less forgiving than the beginner staples: humidity, warmth, and consistent moisture matter.
Care
- Light: Bright indirect keeps variegation strong. Avoid direct sun that scorches pale leaf sections.
- Water: Keep lightly moist; do not let it fully dry for long.
- Soil & potting: Airy, moisture-retentive mix.
- Humidity & temperature: High humidity and stable warmth are important.
- Feeding: Light feeding spring-summer.
- Repotting / propagation: Repot gently and avoid major root disturbance unless dividing.
Propagation
By division only. Separate rooted crowns during repotting, keeping several leaves and healthy roots per division. Recovery is easier with warmth and humidity. See Propagation Basics.
Toxicity
Generally treated as pet-safe. ASPCA lists close Marantaceae houseplants such as prayer plant and rattlesnake plant as non-toxic to cats and dogs; still prevent chewing to avoid stomach upset from plant material.
