This guide explains the main types of hydrangeas grown in the UK, how to recognise them, and what makes each one unique.
🌸 Mophead Hydrangeas (Hydrangea macrophylla)
Mophead hydrangeas are the most recognisable type.
Key features:
- Large, round flower heads
- Blue, pink, or purple blooms (depending on soil pH)

Lacecaps are closely related to mopheads but have flatter flowers.
Key features:
- Flat flower heads with central fertile flowers
- Delicate outer petals
- More natural, airy appearance
- Same colour range as mopheads
Flowering: Old wood
Best for: Wildlife gardens, informal borders
They are excellent for pollinators.

Smooth hydrangeas are extremely reliable and easy to grow.

- Very hardy

They flower well even after hard pruning.

Panicle hydrangeas are known for their cone-shaped flowers.
Key features:

Key features:

- Flat white lacecap flowers
- Vigorous growth
Flowering: Old wood
