Viburnum carlesii (Korean Spice Viburnum)


Michael's Opinion

One of the best Viburnums in my estimation. A well behaved rounded formed shrub of medium stature making it suitable for most types of landscapes. The flowers are of course the highlight of this plant, small rounded clusters that are deeply fragrant. I suggest planting it close to a patio or entrance where the full benefits of its scent can be enjoyed.
