Our Experience
Experience at Great Hill

We have several varieties of viburnum plicatum both on great hill and in our nursery stock. As we do tend to have drier soil, our viburnums can get tired looking during the heat of the summer when drought conditions exist. Supplemental water or shade may be required in these instances. Aside from drought related stress, we have no issues with this viburnum and find it greatly attributes to the landscape with three seasons of interest.

We utilize koreanspice viburnum in several screens and mixed borders throughout the landscape. They’re wonderfully fragrant throughout the spring and can be showy for fall color depending on cultivar.  The majority of our specimens are mature and have surpassed 6’ in height and width. While we have not had an issue with leaf spot, mildew is noticeable some seasons.

The sieboldii featured on great hill are in a big grouping where they’ve grown quite leggy as they’re competing with some large trees for sunlight. Despite not being in as much sun as they’d prefer, they still flower profusely and display a heavy berry set in the fall. Their foliage is very clean and lustrous and even following flowering, their inflorescences linger a rosy red color providing aesthetic value throughout the fall.
