The Snowball Viburnum (Viburnum opulus 'Roseum') is a deciduous shrub known for its striking and abundant spherical clusters of white flowers that resemble snowballs. These large, globe-shaped flower clusters appear in late spring to early summer, starting off as a soft green before maturing to a brilliant white. The plant features dark green, maple-like leaves with three lobes, which turn to shades of red, purple, or yellow in the fall, providing a spectacular autumn display. The shrub has a rounded, bushy habit and a dense foliage, making it an excellent choice for hedges or standalone ornamental features in gardens.
