Viburnum ‘Winterthur’
* Common name: Viburnum ‘Winterthur’
* Botanical name: Viburnum nudum ‘Winterthur’
* What it is: A glossy-leafed, native flowering shrub that gets white flower clusters in late May to June. Berry-sized blue fruits appear in early fall, then the leaves turn a glossy, deep burgundy soon after. Drops leaves in winter. Best fruiting occurs when you’ve got two or more different Viburnum nudums or Viburnum nudum cultivars (such as ‘Brandywine’ and ‘Winterthur’) near one another.
* Size: 5 to 6 feet tall and wide with an annual light pruning.
* Where to use: Nice enough to go out front as a foundation or specimen shrub. Also nice in an island-bed grouping or as a backdrop shrub along a border. Takes full sun or part shade.
* Care: A light scattering of granular, balanced, organic fertilizer each spring is fine. Keep watered in drought at least in the first few years. Prune lightly, if at all, right after flowering.
* Great partner: A backdrop of tall evergreens really sets off the fall foliage. Front with golden mums or dwarf goldenrod for a great fall display.
I planted a Winterthur last fall in Central PA and just bought a Brandywine so it would fruit. What is the optimum and maximum distance to plant it from the Winterthur? Your website is very helpful by the way. Thank you.
Laura,
Right next to each other (about 6 feet apart) would be ideal… in other words, the closer the better. But you should get good cross-pollination even within 100 feet of one another. Even 100 yards away wouldn’t be out of the question.
