The Calathea Medallion is easily identified by its large, round leaves with dark green edges and silver patterns along the midrib. The undersides of the leaves are deep purple, adding a unique contrast to its overall appearance.

Similar Calathea species include Calathea orbifolia, Calathea roseopicta, and Calathea lancifolia, all of which boast their own distinctive leaf patterns.


The Calathea Medallion is a compact plant that typically grows to a height of 12-18 inches (30-45 cm). Its leaves, which can reach up to 12 inches (30 cm) in length, are held upright on long petioles.

As the plant matures, the leaves develop a slight wave, adding visual interest to the foliage. The Calathea Medallion’s growth habit is clump-forming, with new leaves emerging from the center of the plant as it grows.

Light Requirements

Bright, indirect light is optimal for the Calathea Medallion, as direct sunlight can scorch and fade its vibrantly patterned leaves. East- or north-facing windowsills, or a spot near a well-lit window shielded by a sheer curtain, are ideal locations for this plant.

Too little light can cause the plant’s growth to slow and its leaves to lose their vibrant patterns. If you notice these signs, consider moving the Calathea Medallion to a brighter location.

Temperature Requirements

Calathea Medallion thrives in temperatures ranging from 65-80°F (18-27°C). It’s important to protect the plant from drafts, as cold air can damage its delicate leaves.

Ensure that your Calathea Medallion is placed away from drafty windows, air conditioning vents, or heating sources to maintain a consistent temperature.

Humidity Requirements

This tropical plant requires high humidity levels of around 50-70% to thrive. If you notice the leaf tips turning brown or curling, it may be a sign that the humidity is too low.

To increase humidity, you can use a humidifier, place a tray of water with pebbles near the plant, or group it with other humidity-loving plants.

Watering Requirements

Watering is crucial for the Calathea Medallion. The soil should be kept consistently moist but never waterlogged, as this can lead to root rot. It’s best to water the plant when the top 1-2 inches (2.5-5 cm) of soil feels dry to the touch. During the warmer months, you may need to water more frequently, while in the cooler months, you can reduce the watering frequency.

Overwatering can cause yellowing leaves, while underwatering may lead to wilted or drooping leaves. Monitoring the soil moisture and adjusting your watering schedule accordingly will help maintain a healthy Calathea Medallion.

Fertilizing Requirements

Fertilizing the Calathea Medallion is essential for promoting healthy growth. Use a balanced liquid fertilizer, diluted to half-strength, every 4-6 weeks during the growing season (spring and summer). Refrain from fertilizing during the fall and winter, as the plant enters a period of dormancy.

Over-fertilizing can cause leaf burn, while under-fertilizing may result in slow growth and pale leaves. Be sure to follow the recommended application rate and schedule for best results.

Soil Requirements

A well-draining, peat-based potting mix is ideal for the Calathea Medallion. You can create a suitable mix by combining equal parts peat moss, perlite, and potting soil. The addition of perlite improves aeration and drainage, while the peat moss retains moisture, ensuring the right balance for the plant’s roots.

Diseases & Pests

Calathea Medallion is susceptible to some common diseases and pests, including:

  • Root rot: Caused by overwatering, leading to yellowing leaves and wilting. Avoid overwatering and ensure proper drainage to prevent this issue.
  • Spider mites: These tiny pests can cause stippling or yellowing of leaves. Treat with insecticidal soap or neem oil.
  • Mealybugs: These small, white, cotton-like insects can cause leaf drop and stunted growth. Remove them manually or treat with insecticidal soap or neem oil.


The Calathea Medallion is non-toxic to humans and pets, making it a safe addition to homes with children and animals. However, it is still best to keep the plant out of reach of curious pets to prevent any potential damage to the foliage.

Common Problems

Some common issues with Calathea Medallion and their solutions include:

  • Brown leaf tips: This can be due to low humidity, underwatering, or over-fertilizing. Adjust humidity levels, watering schedule, or fertilizer application as needed.
  • Yellowing leaves: Often caused by overwatering, adjust your watering schedule and ensure proper drainage.
  • Faded leaf patterns: This may indicate insufficient light. Move the plant to a brighter location with indirect sunlight.


The Calathea Medallion is a stunning addition to any indoor plant collection, with its vibrant and intricately patterned leaves. By following the care tips provided in this guide, you can ensure your Calathea Medallion remains healthy and beautiful.
