November Plant Profile: Viburnum carlesii

Spicy sweet fragrant flowers in spring followed by red berries in summer and flamboyant fall foliage make the Korean spicebush a superlative shrub for Northwest gardens. The species is named for British botanist and diplomat William Richard Carles, who collected this plant during his voyages to Korea in the late 1800s. Carles was one of the first westerners to journey to Korea, and he sent plants he collected from all around Asia to the Royal Botanic Gardens, Kew. William Botting Hemsley, the director of Kew, gave Carles’s name to this especially delicious smelling Viburnum. With the changing of the seasons our eyes are keenly drawn to bold transformations and gently fading colors and textures in the garden. My colleagues and I have been renovating the Viburnum Collections, and so have had the chance to observe and enjoy how these plants change as the weather becomes colder and wetter. Viburnum carlesii caught my eye for putting on a particularly good fall show. It is vibrant without being ostentatious, with thick pubescent leaves that are currently ranging in shades from green to deep crimson, creating a rather striking effect.

Not only does it look great in the fall, but in spring its pink-tinged buds open to umbels of white, spicy-scented flowers followed by red berries that turn shiny black as summer ends.
