Allegheny serviceberry (Amelanchier laevis) is a native tree/shrub that provides year-round interest. Even after the leaves drop the form of the branches is appealing.
Blue rug juniper (Juniperus horizontalis ‘Wiltonii’) is a low-growing evergreen that is silvery-blue in color. It offers dense coverage and is resistant to deer. As long as the soil isn’t constantly saturated, this is a great option for bringing low maintenance, year-round interest to the landscape.
The Coral Bark Maple (Acer palmatum ‘Sango Kaku’) is a 20-25-foot-tall tree with beautiful foliage that gives way to coral-colored bark in the winter. It makes a lovely focal point with its attractive leaves, fruit and branches.
