Hydrangea arborescens ‘Green Dragon’
Green Dragon Smooth Hydrangea
Hydrangea arborescens 'Green Dragon' is a unique and striking shrub known for its distinctive lime-green flower heads that add a fresh, vibrant touch to the garden. The large, dome-shaped blooms emerge in mid-summer, featuring a mix of tiny fertile flowers surrounded by showy, petal-like sepals, all in varying shades of green. As the season progresses, the flowers take on subtle hints of cream, adding depth and interest to the display.

Design tip
The deeply lobed foliage is as important to ‘Green Dragon’ as its flowers. Treat the unusual leaf shape as a textural feature, allowing it to provide distinctive visual interest throughout the season, before and after the green-to-cream summer blooms.
