Deutzia are shrubs that lose their leaves in winter, typically featuring peeling bark, simple leaves arranged oppositely, and clusters of star-shaped or cupped white flowers that may be fragrant, appearing at the ends of branches or in the leaf axils. 'Nikko' is a small, low-growing shrub that reaches a height of 60cm, characterized by its narrow lance-shaped leaves that often turn a rich purple in the fall, and it produces racemes of tiny white flowers during spring and early summer.
