Goeppertia Medallion (Calathea) — Round Leaf Prayer Plant Care

Goeppertia veitchiana Medallion features large round leaves with intricate green medallion patterns and purple undersides. Master the care of this show-stopping prayer plant. This guide covers everything you need to know about this topic, including common causes, step-by-step solutions, and answers to frequently asked questions.

Here are the key things to understand: Calathea Medallion (now Goeppertia veitchiana) has large round leaves with concentric rings of green shading. The leaf undersides are deep purple-burgundy creating a stunning display when leaves fold upward at night. Grows 1-2 feet tall and wide in a bushy clump that fills out generously in proper conditions. One of the most widely available calatheas found at nurseries, garden centers, and even grocery stores. Despite its availability it maintains the typical calathea temperament regarding water quality and humidity. Understanding these fundamentals will help you diagnose and resolve this issue more effectively.

The most common reasons this occurs include: Crispy leaf edges from tap water minerals — fluoride and chloramine are the primary chemical culprits. Curling leaves indicate underwatering or extremely low humidity below 40%. Leaf spots develop from water sitting on foliage overnight especially in cool poorly ventilated conditions. Spider mites thrive on the dry stressed leaves of calatheas kept in insufficient humidity. Identifying the root cause is the first step toward finding the right solution.

To resolve this, follow these recommended steps: Water with distilled or filtered water when the top inch of soil feels dry — maintain even moisture. Provide bright indirect light — the large round leaves catch more direct light so be cautious of sunburn. Keep humidity above 55% consistently, using a humidifier rather than misting which can cause leaf spots. Inspect leaf undersides regularly for spider mites which appear as tiny specks with fine webbing. Repot every 1-2 years in spring using a mix of peat or coco coir, perlite, and orchid bark. If these steps do not resolve the issue, consider consulting additional resources or a qualified professional.
