Korean Spice Carlesii Viburnum Flowering Shrubs

The Korean Spice Carlesii Viburnum is shorter growing than the Judd Viburnum, but packs a huge punch as a fragrant flowering shrub. March and April will find your Carlesii Viburnum covered with cluster like blooms up to 3 inches across. Large broad, oval dark green leaves with serrated edges provide an excellent backdrop for the clustered white blooms. Prune after flowering to remove dead or broken branches and for shape as the plant will set buds by mid to late summer.

Do you have black walnut trees growing in your yard? Then, you’ll be thrilled to know that the Korean Spice Viburnum tolerates the juglone poison of the Black Walnut tree. Plant in full to part sun. You’ll enjoy how the blue-black fruit that appears in late summer attracts birds to your yard.

This Korean spice grows into the 4 to 6 foot height range and 4 to 7 feet wide. The dark green foliage turns red in fall…sometimes wine to burgundy shades. An excellent spring flowering shrub that is sure to be an attraction year after year. Pairs nicely with the Juddi Viburnum.

Koreanspice Viburnum Information

Koreanspice viburnum (Viburnum carlesii) is one of over 150 known Viburnum plant species and cultivars. While viburnums can be both deciduous and evergreen and reach up to 30 feet in height, Koreanspice viburnum plants are deciduous and known for their relatively small, compact growing habit. They tend to grow to between 3 and 5 feet tall and wide, but they can reach as high as 8 feet in ideal growing conditions.

Koreanspice viburnum plants produce 2- to 3-inch wide clusters of small flowers that begin pink and open to white in early to mid-spring. The flowers give off a rich scent that is similar to spice cake. These flowers are followed by blue-black berries. The 4-inch leaves are ridged and deep green. In autumn, they turn deep red to purple.

How to Grow Koreanspice Viburnums

The best conditions for growing Koreanspice viburnum plants include moist but well-draining soil and full sun to partial shade.

Koreanspice viburnum care is very minimal. The plants don’t need much in the way of watering, and they suffer from very few pest and disease problems. They are hardy in USDA zones 4 through 9, but they may need some winter protection, especially from the wind, in colder zones.

Koreanspice viburnum plants should be pruned in the spring immediately after flowering has ended. The pruned green cuttings can be used effectively as starts if you’re looking to propagate new plants.

Viburnums Are Versatile Shrubs

Viburnums that excel from season to season

I would be hard pressed to pick just a handful of exceptional viburnums, so this hefty chart lists a few dozen. Bloom times are for Zone 6. Semi-evergreen means that the shrub holds some or all of its leaves in a mild winter. Unless noted, viburnums grow well in moist, well-drained soil in full sun, but will also tolerate partial shade. North American native viburnums and their cultivars are indicated by an asterisk.
