About this plant
The rounded flower heads make a hydrangea a substantial seasonal feature. Blue colour is influenced by growing conditions and soil chemistry, so it may change after repotting.
Care at a glance
- Light
- Partial shade, sheltered from hot afternoon sun
- Watering
- Keep evenly moist, especially during flowering
- Soil
- Moisture-retentive, free-draining compost
Plan your care
Choose the plant for its flowers and shape while allowing for colour changes. A blue label is not a guarantee that future flowers will remain blue under different soil conditions.
Leave room for the broad leaves and enough pot volume to buffer drying. Before pruning, identify the variety and its flowering habit; cutting every stem down can sacrifice the following display.
Growing tips
Do not let a flowering pot dry out completely. Avoid cutting all stems back hard: many mophead hydrangeas flower on growth made the previous year. Blue colour is not guaranteed by the plant label alone.
