Snowballs in summer? With big & bold round white clusters of flowers hanging from the branches in May & June, it's understandable that this magnificent shrub should be known as the Snowball Tree. The leaves of Viburnum opulus ' Roseum' turn to shades of red & violet in autumn, making a wonderful display. Unlike the species, this variety is sterile so it wont produce berries. This shrub thrives in sun or full shade, is easy to grow & maintain, & holds the RHS Award of Garden Merit. Height & spread: 4m (13').
