Design IdeasSteeplechase may be the best hedging evergreen on the market today. Use to block out adjacent multistory buildings or unsightly land uses. Narrow enough to run in gaps between driveways and in side yards. A superior choice to enclose outdoor living spaces for year around privacy. Well suited to a wind protection screen and may be useful in mitigating traffic noise as sound attenuation barrier.

Companion PlantsTrees with vivid color stand out boldly against this evergreen background. Try Saratoga Maidenhair Tree, (Ginkgo biloba 'Saratoga'), Summer Red Maple, (Acer rubrum 'Summer Red'), Purple Fountain Beech, (Fagus sylvatica 'Purple Fountain'), and Black Tulip Magnolia, (Magnolia soulangiana 'JURmag1'). Very nice against Golden Spirit Smoke Tree, (Cotinus coggygria 'Ancot')

Follow a regular watering schedule during the first growing season to establish a deep, extensive root system. Feed with a general purpose fertilizer before new growth begins in spring. For a tidy, neat appearance, shear annually to shape.
