Calathea medallion variety has dark-purple foliage with a prominent silver-colored midrib, or central leaf vein, on the round to oblong leaves. Calatheas, also called zebra plants, are tropical plants that consist of about 300 different species. Grown as houseplants in most regions, calathea plants are prized for their variegated, colorful foliage and reach a height of 6 to 36 inches at most.
Position the Calathea medallion plant in indirect sunlight. Keep the plant away from direct sunlight because this will scorch the leaves. Calathea medallion plants enjoy lower light levels, high humidity and moderate soil moisture. For best results, maintain a regular watering schedule and keep your Calathea Medallion moist, but not wet or saturated. This is not a drought tolerant indoor plant, but it is relatively forgiving if you forget to water it from time to time. Extended periods of dryness can result in brown leaf tips or edges.
Watering
Water once a week or when the soil starts to become slightly dry at the top. Keep the soil lightly moist at all times, but do not overwater as this will cause brown spots and leaf drop. Curly or dry leaves suggest, the plant is dry and needs watering. Water in the early morning or late evening when temperatures are cooler. Always check your soil before watering.
