Doublefile Viburnum is a deciduous shrub that grows up to 8ft tall and could reach 10 ft wide with long tiered branches that shoot out horizontally, topped with large clusters of white flowers in spring. Foliage may turn fall colors depending on your area and produce ornamental berries in autumn. Grows in partial to full sun in zones 5-8.  Would be gorgeous towards the back of your border as a back drop for all your other spring blooming beauties.
