Viburnum

Viburnum plicatum f. tomentosum ‘Summer Snowflake’ – A superb introduction from the University of British Columbia with continuous white lacecap blooms from May to September. This cultivar of Doublefile Viburnum is deciduous and of Japanese origin. It can be maintained to 4-5′ tall and wide with pruning, but is capable of growing up to 8-10 feet. Hardy to zone 6.

Viburnum davidii – This evergreen shrub is most commonly used in foundation plantings and tolerates part to full sun (it won’t bloom well in the shade). The white flowers are present in late spring and these are followed by attractive metallic blue berries on female plants (retail shrubs aren’t usually sexed). The deeply veined foliage can be maintained at 3′ tall and 4′ wide. Hardy to zone 7.

Viburnum dentatum ‘Blue Muffin’ – This cultivar of Arrow-Wood Viburnum produces creamy-white flowers from late spring to midsummer. These are followed by abundant blue berries (requires a cross pollinator, try ‘Chicago Lustre’) that attract birds. The glossy serrated foliage (deciduous) turns a yellowish-purple to red in fall. Grows 5-7′ tall and 4-5′ wide. Hardy to zone 3.

Viburnum tinus – Laurustinus Viburnum is a medium to large-sized evergreen shrub with fragrant white flowers that emerge from pink puds in late autumn and again in early spring – it also produces attractive metallic blue berries. Two good cultivars include ‘Spring Bouquet’ (compact) and ‘Gwenllian’ (vigorous). Trimmed height 4-6′ tall, up to 8′. Zone 7-8 hardy.

Viburnum rhytidophyllum – Leatherleaf Viburnum is not a common sight these days, much in part to its large size of 10-15′ tall and 12′ wide (can be maintained smaller). It bears 8″ wide round clusters of white flowers in late spring, followed by red fruits that mature to black. The 6-8″ long tapered leaves are deeply veined and hang downwards. Hardy to zone 6.
