The Amazonian rainforests of Brazil are Calathea Triostar’s natural home. Known as Prayer Plants due to the way the leaves close upwards at night, these wonderfully air purifying houseplants will bring a splash of tropical colour to your space and are well worth the misting effort.

Native to Brazil
Positioning + Light Needs
Requires good levels of natural light but avoid any direct sunlight. It is wise to place your plant somewhere where it can be watered and misted with ease, but avoid positioning next to radiators or draughty windows or doors.
Soil needs to be kept moist so water weekly but never soak. Make sure to water less frequently in winter. N.B. If you can, avoid hard tap water; use instead filtered or rain water.
Calatheas enjoy humidity in their natural climate, so its a must to replicate this! A quick mist daily or alternatively you can seat the pot on a tray of pebbles with water inside. 
Feed once every 2 weeks during the growing season from April – October with a diluted liquid feed. 
Every 2 years should be fine, Springtime is best.

Browning leaves: possibly needs greater humidity. 
Muted colour / variegation: increase the light exposure, being careful to avoid direct sunlight.
