Viburnum plicatum ‘Grandiflorum’ is a deciduous shrub selected for its generous proportions and notably large flower clusters. It develops a wide framework of horizontally arranged branches, creating a structured outline that gives the plant presence well beyond its flowering period. In late spring to early summer, substantial rounded heads of white flowers appear along the branch tiers, producing a bold yet orderly display that emphasises the shrub’s architectural form. Throughout the growing season, the pleated foliage provides a steady backdrop before shifting subtly in autumn. Best suited to gardens where space allows its natural shape to be fully expressed, ‘Grandiflorum’ offers long-term structure and scale with minimal need for intervention.
