Mophead and lacecap hydrangeas can change colour depending on soil pH. Acidic soil produces blue flowers, while alkaline soil results in pink blooms.

This is often caused by pruning at the wrong time or late spring frost damaging developing buds. Mophead varieties flower on older wood, so timing is important.

For full sun and modern borders

Choose Hydrangea paniculata Varieties like ‘Limelight’ and ‘Pinky Winky’ tolerate more sun and flower on new growth, making them reliable and easy to prune.

For shade and north-facing spots

Mophead (macrophylla) and lacecap (serrata) hydrangeas are best suited to partial shade. These traditional varieties thrive in cooler conditions and produce large, colourful blooms.

For patios and containers

Compact varieties such as ‘Bobo’ or the Endless Summer range are ideal for pots. They stay manageable in size while still producing long-lasting flowers.

For autumn colour and foliage interest

Oakleaf hydrangeas (quercifolia) stand out for their distinctive leaves, which turn deep red and bronze in autumn. Varieties like ‘Snowflake’ offer both flowers and seasonal colour.

For walls, fences and vertical spaces

Climbing hydrangeas are perfect for covering walls, fences, and shaded structures. They establish slowly but become very reliable, producing delicate lacecap-style flowers once mature.

For large blooms and bold garden impact

Hydrangea arborescens varieties, such as ‘Annabelle’, are known for their large, rounded flower heads and strong performance in both sun and partial shade. They flower on new growth, making them easy to prune each year.
