Description
Calathea comes from the rainforests of South and Central America. The genus includes about 150 species, around 30 of which are grown as ornamental plants. They are evergreen perennials which in the right conditions can grow up to 1 metre tall. All species have large leaves on long or short stalks, oval or elongated, striped or spotted, brightly coloured and patterned. Some are tinted pink or purple. They flower in spring and summer, but only one species, Calathea crocata, is grown for its decorative flowers.
Requirements
As it comes from forests, during growth it is not too demanding about light – it can be a bright spot (but not direct sun) or partial shade. For good growth it needs warmth – at least 22°C by day and 16°C at night – and a humid position all year round. It also needs high air humidity, so it is good to mist it often.
Propagation
It is propagated by division and from tip cuttings.
Care
Plant in a light, loose compost with a high peat content, and use a thick drainage layer in the pots. Pay particular attention to watering. Keep the compost constantly moist and mist often, but do not overdo it, as excess water can also cause harm. Water and mist with soft, lukewarm water. Feed during the growing season.
