Position
Full sun with light shade, preferably morning sun and arvo shade. While they like an acidic soil, avoid planting near a concrete wall or near anything that might make the pH too high.
Watering
Keep soil moist but not too wet. You can give them an extra drink with daily misting (using a spray bottle).
Care
They need attention and love. Extra humidity is important. Cut off the faded flowers to encourage continuous blooming.
