Korean spice viburnum

The semi-snowball white flowers of fragrant viburnum

Korean spice viburnum's most notable characteristic is the intoxicating fragrant white flowers that cover the shrub in spring.  The pink to red budded white flowers have a pink blush, leaves are a dull, dark green that turn outstanding wine-red in the fall.  An excellent choice as specimen, in a shrub border, and as a foundation plant. Place it where the fragrant flowers can be enjoyed.
