Corona Prayer Plant

Botanical Name: Calathea sp. 'Corona'

Corona Prayer Plant deserves its place among the showy plants of the Maranta (Marantaceae) family.

Its broad, silvery-green leaves taper to a point and are edged with a wide band of dark green.

'Corona' is one of the most popular among the named varieties in the Calathea genus. Its handsome markings and colors make it easy to see why.

New leaves are curled as they emerge, showing their purplish red undersides. And like its family members, this tropical foliage plant folds its leaves at night as hands in prayer.

The secret to keeping it happy is to provide high humidity. Brown leaf tips indicate the air is too dry. Do anything you can to keep the relative humidity above 50%. Place it on a humidity tray or use a room humidifier. Calatheas also love to be misted with rainwater.

Display Ideas: Group calatheas with other humidity-loving plants, such as bromeliads and ferns. Or show off a single plant by placing it on a pedestal plant stand.

Repot calathea in spring to give it fresh potting mix. Need a new container? Check out stylish, new house plant pots here.

Watch for spider mites. Dry indoor air in the winter months encourages these pests to invade house plants, another reason to keep the humidity up. You'll first notice faint webbing on the undersides of leaves. Don't use an oil-based insecticide on Calatheas because it will damage those beautiful leaves. And if your plant is badly infested, get rid of it.
