Mohawk is surely one of the finest fragrant viburnums that has ever been bred. In fact, it is a testament to the amazing results that can occur from the best efforts of talented and dedicated plant breeders. One of the parent plants of Viburnum x burkwoodii is Viburnum carlesi (Koreanspice Viburnum). Carlesi is an incredibly fragrant plant. On a warm and calm spring day, it can perfume an entire garden with its exotic spicy scent. Many think it is the most heavenly fragrant garden plant. However carlesi does have some drawbacks. Its dull green foliage is not particularly attractive, it is fairly susceptible to bacterial leaf spot, and it is not the most adaptable garden shrub. Enter Viburnum utile, stage left. When utile and carlesi were crossed,  the offspring was named x burkwoodii. Burkwood Viburnum displays the best of both parents. The flowers and amazing fragrance come from carlesi and the glossy attractive foliage, lovely fall color, and resistance bacterial leaf spot are inherited from utile.

The late Don Egolf, the incredibly talented and prolific plant breeder at the U.S. National Arboretum, took x burkwoodii breeding a step farther by backcrossing it with carlesi to produce an offspring that was ¾ carlesi and ¼ utile. The best of these offspring was named Mohawk and released to the trade in 1966. Mohawk is distinguished by its numerous dark-red flower buds that open to incredibly fragrant, waxy, white flowers with red blotches on the reverse side of the petals. The buds are themselves highly ornamental for several weeks before they open. The foliage is glossy-green that and turns a brilliant orange-red in fall. It is also quite adaptable culture-wise and highly disease resistant.
