Calathea Medallion Care Guide
Calathea medallion (Goeppertia veitchiana) is one of the most widely available calatheas and one of the more forgiving for indoor growing. It produces large, rounded leaves with a bold medallion or feather pattern in silver-green and darker green on the upper surface and a deep burgundy-purple underside that becomes visible when the leaves fold at night. It grows to a medium-large size, typically 50 to 70 centimeters tall and wide at maturity, making it a substantial indoor plant. The care requirements are consistent with the Marantaceae family as a whole, with water quality and humidity being the two factors that most directly affect long-term health.
Quick Reference
| Factor | Requirement |
|---|---|
| Light | Medium to bright indirect light |
| Water | Filtered or rainwater; keep consistently moist |
| Humidity | 60 percent or above |
| Temperature | 18 to 27 degrees Celsius |
| Soil | Moisture-retentive, well-draining mix |
| Fertilizer | Balanced liquid fertilizer monthly, spring through early autumn |
| Pot | Container with drainage holes |
| Toxicity | Non-toxic to cats and dogs |
Light
Calathea medallion grows best in medium to bright indirect light. It tolerates lower light reasonably well, more so than white fusion or orbifolia, but growth slows considerably in dim conditions and the intricate leaf pattern becomes less vivid. Avoid direct sun, which bleaches the surface pattern and causes the leaves to curl or develop pale, scorched areas.
Water and Water Quality
Keep the potting mix consistently moist without allowing it to become waterlogged. Water when the top centimeter of mix is dry. Use filtered water, rainwater, or tap water left to stand for 24 hours. Tap water high in fluoride or chlorine causes the brown tip damage that is the most common problem in this species. If brown tips are already present, switch water type and the damage will stop progressing, though existing browning does not reverse. The full diagnosis is in the brown tips and crispy edges guide.
Humidity
Aim for 60 percent humidity or above. Calathea medallion is slightly more tolerant of typical household humidity levels than more demanding species, but it performs noticeably better with consistent humidity support. A humidifier is the most effective solution.
Soil, Fertilizing, and Repotting
A blend of coir, perlite, and potting compost provides a free-draining but moisture-retentive base. Fertilize monthly during the growing season with a balanced liquid fertilizer at half strength. Avoid heavy feeding, which causes salt accumulation and root damage. Repot in spring every one to two years or when roots are filling the current container, moving up one pot size at a time.
