Grown for interior display, this hydrangea does best in bright, indirect light and a cool room (10–18°C or 50-65°F), kept away from radiators and direct sun. Keep the soil consistently moist, ideally using room-temperature rainwater, and maintain humidity and good drainage with a pebble tray. Feed every two weeks while flowering with a balanced liquid fertiliser to support growth. Indoors it needs only light attention, such as removing dead leaves and faded blooms, and it will look its best for around 4–8 weeks before needing to be moved outside.
When planting it outdoors, remember that flower colour will shift to pink unless the soil is acidic. Leave old flower heads on the plant through winter for protection. Gradually acclimatise it to outdoor conditions in late spring before planting once frost has passed.
