Calathea Roseopicta ‘Corona’, a stunning cultivar of the Calathea Roseopicta species, hails from the tropical rainforests of Central and South America.
The plant is a part of the Marantaceae family, which is popularly known as the prayer plant family.
The name “prayer plant” comes from the unique feature of these plants to raise and lower their leaves during the day and night, resembling hands in a praying position. This movement, known as nyctinasty, helps the plant optimize its exposure to sunlight and conserve water.
The ‘Corona’ cultivar is characterized by its large, oval leaves with dark green backgrounds adorned with striking silvery patterns that resemble brush strokes.
The leaves’ undersides feature a rich, purple hue that adds to the plant’s visual appeal. The plant has a compact growth habit, with leaves emerging from a central rosette.
Calathea Roseopicta ‘Corona’ is a relatively slow-growing plant, adding just a few leaves each year. Although the plant rarely blooms indoors, it may produce small, white flowers surrounded by green bracts when grown outdoors in the right conditions.
Caring for Your Calathea Roseopicta ‘Corona’
- Light: Your Calathea Roseopicta ‘Corona’ will thrive in bright, indirect light. Avoid direct sunlight, as it can scorch the leaves, damaging the plant’s appearance. Place your plant near an east or north-facing window, or use sheer curtains to filter light from a south or west-facing window.
- Water: Calatheas prefer consistently moist soil. Water your ‘Corona’ when the top 1-2 inches (2.5-5 cm) of soil feels dry to the touch. Use room temperature, filtered, or distilled water to avoid the build-up of salts and minerals in the soil. Overwatering can lead to root rot, so make sure your pot has drainage holes.
- Humidity: As a tropical plant, Calathea Roseopicta ‘Corona’ loves high humidity levels. Aim for 50-60% humidity in your home, achieved by placing the plant on a tray of water-filled pebbles, using a humidifier, or regularly misting the leaves.

Facts about the Plant
- Calathea plants are non-toxic and safe for pets, making them a popular choice for pet owners.
- The leaves of Calathea plants, including the ‘Corona’ variety, move up and down throughout the day, following the sunlight. This movement is called nyctinasty and is controlled by the plant’s circadian rhythm.
- Calatheas are considered to be natural air purifiers, as they absorb certain volatile organic compounds (VOCs) from the air and release oxygen during the process of photosynthesis.
- The Calathea genus is native to the tropical rainforests of Central and South America, where they grow on the forest floor, receiving dappled sunlight through the canopy.
- In their natural habitat, Calathea plants are pollinated by insects, such as bees and butterflies.
Tips to Grow This Plant
- Pot Selection: Choose a pot with drainage holes to prevent waterlogging and root rot. A pot made from porous materials like terracotta can help maintain proper soil moisture levels.
- Repotting: Repot your Calathea Roseopicta ‘Corona’ every 1-2 years or when the roots become visible at the bottom of the pot. Use a well-draining soil mix and a slightly larger pot to encourage healthy growth.
- Fertilizing: Fertilize your plant every 4-6 weeks during the growing season (spring and summer) using a balanced, water-soluble fertilizer diluted to half strength. Avoid over-fertilizing, as it can lead to leaf burn and other issues.
- Pruning: Prune yellowing or damaged leaves to encourage new, healthy growth. Use clean, sharp scissors to make clean cuts at the base of the leaf stem.
Some common problems faced by Calathea Roseopicta ‘Corona’ owners include:
- Leaf curling or crisping: This can be a result of low humidity or underwatering. Increase humidity levels and maintain consistent soil moisture to combat this issue.
- Brown leaf tips: This is often caused by exposure to direct sunlight or the use of tap water with high levels of chlorine or fluoride. Use filtered or distilled water and ensure your plant receives indirect light.
- Root rot: Overwatering or poor drainage can lead to root rot. Monitor your watering routine and ensure your pot has proper drainage holes to prevent this issue.
Care and Maintenance
- Keep an eye on humidity levels: As a tropical plant, Calathea Roseopicta ‘Corona’ thrives in humid environments. Maintain a humidity level of 50-60% for optimal growth.
- Consistent watering: Water your plant when the top 1-2 inches (2.5-5 cm) of soil feel dry to the touch. Use room temperature, filtered, or distilled water to avoid salt and mineral buildup.
- Temperature: Calathea Roseopicta ‘Corona’ prefers temperatures between 65-85°F (18-29°C). Avoid placing your plant near drafts, air conditioning vents, or heaters, as sudden temperature fluctuations can stress the plant.
- Pest control: Check your plant regularly for common pests like spider mites, aphids, or mealybugs. If you spot any infestations, treat them immediately with insecticidal soap or neem oil.
