Shrub Viburnum × burkwoodii [Burkwood Viburnum] Trouble-free plant tolerant of soils and pollution (except sulfur). Also, does not tolerate more severe drought. Very fragrant when in bloom, although to a lesser degree than Viburnum carlesii (Koreanspice Viburnum). Bacterial spot and powdery mildew susceptibility (but not always a problem). Sulfur containing pesticides burn or defoliate leaves. Too thin to be a solid screen.
Shrub Viburnum × burkwoodii 'Chenaultii' [Chenault Burkwood Viburnum] 'Chenaultii' has a finer-textured, more delicate appearance than the species type due to its smaller leaves and thinner branches. Trouble-free plant tolerant of soils and pollution (except sulfur). Also, does not tolerate more severe drought. Very fragrant when in bloom, although to a lesser degree than Viburnum carlesii (Koreanspice Viburnum). Bacterial spot and powdery mildew susceptibility (but not always a problem). Sulfur containing pesticides burn or defoliate leaves. Too thin to be a solid screen.

Pink buds open to clusters of white fragrant flowers in May. Leaves change from a dark green to a vibrant orange-red in the fall. Bacterial leaf spot can be a problem in some settings. Prune immediately after flowering for best flower show the next year.
Shrub Viburnum × rhytidophylloides [Lantanaphyllum Viburnum] Poor tolerance to heavy wind environments. Planting in groups of different clones will help increase fruit production.
