Calatheas are the go-to foliage plants when looking for showy, interesting leaves, and Medallion III is no exception. Medallion III Calathea (Calathea roseopicta, also called Peacock Plant and Zebra Plant) is a variety with dark-green, slightly rippled leaves that look like they have been dry brushed with silvery-green paint, fanning out from the midrib. Like other Calatheas, the Medallion III experiences nyctinastic movement, its leaves responding to changes in light by dancing throughout the day. Given humid conditions, plenty of indirect light, and consistently moist soil, the Medallion III Calathea is a great pet-safe plant.

Best Locations For Growing Medallion III Calathea

With the reputation of being a fussy plant, Calatheas do best when kept in a bright spot where the soil moisture can be checked regularly and the leaves can receive plenty of humidity. For this reason, place the Medallion III Calathea in a bright bathroom or kitchen window with easy access to water and slightly higher humidity levels. Calatheas are non-toxic, making them safe for homes with pets and children. 

Medallion III Calathea Sunlight Requirements

The Medallion III Calathea will thrive in medium to bright indirect light but can burn easily in direct sunlight. Place this plant in a north- or east-facing window or near a west- or south-facing window, protected from harsh afternoon sunlight. These plants can do well in the interior of a room if it is a bright space. 

Medallion III Calathea Care

It is possible to keep Calathea leaves healthy and colorful with consistent attention and care. Calatheas originate from tropical, humid forest floors, and therefore thrive when provided with a humidifier, pebble tray, or regular misting. If the leaf edges become dry and crispy, the plant may not be getting enough humidity or the soil may have dried out too much. The soil of the Medallion III Calathea should be kept consistently moist but not soggy. Repot this plant every two years or so into a pot with drainage holes and well-draining peaty soil. 

Watering Medallion III Calathea

Calatheas are intolerant of drying out, which often causes the beautiful leaves to shrivel, dry out, or form crispy edges. Because of this, the Medallion III Calathea may need to be watered every few days to keep its soil consistently moist. Allow the soil surface to dry in between waterings and water deeply until water comes out the bottom of the pot. Always keep Calathea in well-draining soil and a pot with drainage holes to prevent root rot. In the winter, watering may be cut back slightly, though the plant’s need for humidity may still be high. 

Feeding Medallion III Calathea 

Calatheas appreciate regular fertilizing during their growing season. Spring through summer, feed the Medallion III Calathea liquid indoor plant food once a month. Always take care to follow dilution recommendations when using fertilizer, as over-fertilizing can often damage plant roots and leaves. There is no need to fertilize in the winter as plants slow down their growth or even go dormant.

Plant Addicts Warranty - 1 Year (Extra Purchase Required)

We encourage all plant lovers to purchase the Plant Addicts Warranty, whether you're a new gardener or an expert. There are many variables outside of anyone's control that can cause a plant to die.

The warranty is purchased on a per plant basis and must be purchased at the same time as the plant(s). We will cover 100% of the price of the plant, but the warranty does not cover shipping costs. SImply let us know if your plant has died within 1 year of receiving it and we will get you a new one shipped out as soon as possible (depending on the time of the year and availability).

Plant Shipping

Below are some factors we consider when determining when to ship the plants depending on the timing of the order.

Winter to Early Spring

We ship only when it's warm enough to plant in your growing zone.
Sometimes plants aren't completely ready to sell and ship in early spring. We will wait until the plants are ready before shipping so you don't get a subpar product.
For Southern plants we will be able to ship much earlier than plants coming from our northern nursery.


If there is extreme heat we may delay shipping for a week or several weeks.
We review what areas the plants are traveling through as well as your location.

Fall into Winter

We’ll ship plants out all the way up to the end of the fall planting season!


Get your order in early to reserve your plants for Spring planting!

Once your plant is shipped you’ll receive an automated email with tracking information.
