Viburnum × burkwoodii (Burkwood viburnum). This evergreen species produces shiny dark green foliage. The flowers have intense fragrant clusters of white blooms and appear in the spring and summer. This is an excellent choice for the home landscaper, as it provides all year-round greenery and a stunning spring to summer floral show.
They are fully to frost hardy and will grow in sun or semi-shade in deep, fertile not too dry soil. To thin out overgrown plants cut out some older shoots after flowering.
