About this plant
What makes this plant special
'Blaumeise' (syn. 'Blue Sky'), a Swiss lacecap from the 1979 Teller series, holds the RHS Award of Garden Merit. Tall, dependable and quick to turn blue, it has sturdy upright stems of 1.8 to 2 m that seldom splay. Each 12 to 15 cm head is ringed by about ten intense blue florets, turning pink on neutral or chalky soil.
Hydrangea
Hydrangeas are shrubs and climbers from East Asia and the Americas, grown for their large flower heads in which showy sterile florets ring or hide the small fertile flowers. Many grow wild along woodland edges, in filtered light and in acid, humus-rich soil that holds moisture yet drains freely; a pH between about 4.5 and 7 suits them best. They flower for weeks in summer.
Lacecap Hydrangea macrophylla
The bigleaf hydrangea grows wild along the low-lying east coast of Japan and is the classic garden hydrangea, with broad leaves and round mophead or flat lacecap heads. Most varieties flower in July and August, a few from June or into late autumn, and the slowly fading heads stay decorative for months. Pink varieties turn blue only in acid soil containing enough aluminium; white and red ones hardly change.
Location and soil
Happiest in partial shade with a few hours of sun, but out of the midday sun, or in dappled light beneath deep-rooted trees; in heavy shade it flops and flowers poorly. It needs acid to neutral soil that holds moisture well, as the large leaves use a lot of water. Not every variety is fully hardy and the buds are sensitive to late frost, so shelter it from east and north winds.
Pruning and care
Flowers mainly on the previous year's wood, and next year's buds form in August just below the old heads, so never prune in autumn. In April remove the faded heads and, once the shrub is in leaf, any dead wood; on plants older than five years also cut a few of the oldest stems to the ground. Feed sparingly in March and August, and cover with fleece in hard or late frosts.
Use in the garden
A mainstay for borders, shady beds, informal hedges and foundation planting, and compact varieties do well in pots on a terrace or balcony. The flower heads are also good for cutting and drying.
