Calathea have been reclassified to the genus Goeppertia, you will see this plant labelled as Calathea vittata - its true name is Goeppertia elliptica.
Goeppertia elliptica is part of the Marantaceae family and its native range of this species is Colombia to N. South America and N. & NE. Brazil where it grows as a perennial primarily in the wet tropical biome.
Leaves are light to mid green with very pale green - white markings running parallel to the veins.
Genus name Goeppertia honours German botanist, Johann Heinrich Robert Goeppert. The specific epithet refers to the shape of the leaves.
Light: Even if this plant doesn’t see the sun but receives indirect light all day, it will put out new growth, however, for optimum growth and pronounced variegation, provide this plant with bright indirect light, meaning the plant sees the sun for 0-4 hours per day - this could be through trees or a translucent curtain.
Water: Given adequate light, keep the potting mix evenly moist. If the soil dries out too much, the plant will become limp, aerate the mix with a few pokes of a skewer or blunt stick, pour water slowly over the top and allow the water to pass through the drainage holes. Over the next day or so, the leaves will perk up.
Potting mix: A well draining mix composed of coco coir, perlite, a little bit of orchid bark and worm castings. Adding a small amount of sphagnum moss will help to retain moisture in the mix.
Fertilising: Feed your plant every other watering during the growing season or when you observe active growth. You can dilute fertiliser to half the recommended amount but never add more.
Temperature: 18-23°C. Keep it away from draughts and nearby heating or cooling appliances.
Humidity: Calathea benefit greatly from high humidity levels. Using a humidifier, or placing the plant on a tray of pebbles with water can prove very helpful. Dry air can cause the leaf edges to become brown and crispy.
Calathea are non-toxic.
