Sargent Viburnum Onondaga is a deciduous shrub known for its dark purple-red foliage that emerges in spring and matures to green, providing a stunning contrast to the lacecap-like clusters of white flowers with red-purple buds. Growing to about 2-3m in height, it adds interest to mixed borders or as a specimen plant. The autumn foliage turns a brilliant red, enhancing its seasonal appeal. It prefers full sun to part shade and well-drained soil.
