Editorial revision:
Care at a glance
Light
Bright indirect or filtered light in a cool room. Avoid harsh direct sun through glass which scorches petals and leaves.
Watering
Keep the lime-free ericaceous compost consistently moist. Water by bottom immersion with rainwater; hard tap water triggers chlorosis.
Conditions vary with pot, season and location. Always check the mix and your plant's response.
How to identify it
Compact evergreen woody shrub with small leathery dark green leaves and profuse single or double flowers in vibrant pink, red, or white.
Environment and placement
Cool, well-ventilated positions (12-16 °C / 54-61 °F). Dry central heating causes rapid shedding of flower buds and foliage.
