Hydrangea 'Snowflake' is a deciduous shrub with a bushy habit, typically reaching a height and spread of up to 2.5m. Its bold, lobed leaves resemble those of an oak tree, turning vibrant shades of orange and purple in autumn, adding stunning seasonal interest. In spring, the plant produces panicles of double white flowers, which gradually fade to pink by autumn, complementing the changing foliage. This hydrangea thrives in moist but well-drained to well-drained soils and prefers a position in full sun to partial shade.
