Viburnums are a gardener's favorite; they're one the most useful and versatile shrubs available. With over 120 varieties there's one for any garden project. Some viburnums, such as the arrowwood or maple-leaf, are wonderful as woodland garden shrubs. Others have a more formal feel such as the Korean spice or judii varieties and are suitable for foundation plantings, shrub borders and as specimen plants.
Viburnums add year round interest to the garden. White and cream colored flowers bloom in the spring. Some viburnums, such as the Korean spice, are valued for their intense fragrance. Others, however, are noted for their unpleasant scent. Vibrunums are a full growing shrub with lush foliage through the summer. In the fall, many varieties, such as the arrowwood and European cranberry bush, provide the landscape with brilliant shades of orange and red. Colorful red, purple, or blue berries brighten the garden and contrast against the snow in winter. The berries also provide food for birds. They're also adaptable to many site conditions.
Viburnums prefer rich, moist, organic somewhat acidic soils. Prepare for planting as you would any shrub. Dig a hole approximately twice as wide as the root ball and just as deep. Place the viburnum in the hole, making sure the top of the root ball matches the existing grade of the garden. Never install any plant below grade, its often detrimental to the health of the plant. Backfill about half way and water to remove air pockets. Finish filling the hole, water again and mulch. Planting in the spring or fall is best as the hot summer weather can stress viburnums.
