Spiraea ‘Double White May’ is a timeless garden favourite prized for its glorious arching branches laden with clusters of double, snow-white blooms in late spring. This fast-growing deciduous shrub adds a classic elegance to cottage gardens and borders, flowering in abundance and creating a soft, romantic effect.

The plant thrives in full sun to part shade and grows best in well-drained soil. Once established, it is drought-tolerant and low maintenance—ideal for gardeners of all skill levels. Light pruning after flowering keeps it tidy and promotes dense growth and future flowering.

Its fountain-like form and prolific blooming make it perfect as a feature plant, informal hedge, or planted en masse for a breathtaking spring display. Whether you're designing a cottage garden or refreshing a large landscape, Spiraea ‘Double White May’ brings lasting charm and seasonal impact.
