Calathea 'Elgergrass' is a striking indoor houseplant which produce pale green narrow leaves. Most of the steam are in a vibrant shade of red and like most of the Calathea species, this plant goes to sleep every night by rolling its leaves into and upright position. These plants can grow to an impressive 80cm in height and is a air purifying plant!
Water every 1-2 weeks, allowing soil to dry out half way down between waterings. Expect to water more often in brighter light and less often in lower light.
Apply a weak dose of a nitrogen rich foliage fertiliser once or twice a month during the growing season.
