Pennsylvania Sedge is a low-growing, semi-evergreen perennial sedge, which grows well in shade. The bright-green, arching, grass-like leaves grow in soft clumps. This plant spreads by rhizomes (underground stems) to form a nice groundcover.
Gray Birch is a medium-sized, short-lived deciduous tree with chalky white bark. It grows best in areas where the soil is shaded, cool, and moist. Keep the shallow root system moist by using mulch and watering during dry weather. This tree can be short-lived in New Jersey. It does not tolerate heat and humidity well, and grows best in areas with cool summers. Use Gray Birch in rain gardens and other areas of the yard with moist soil conditions, or in woodland gardens.
Paper Birch is a short-lived deciduous tree with beautiful, white bark that that peels in papery strips. Catkins (elongated, drooping clusters of tiny flowers without petals) appear just before the leaves emerge. The flowers are followed by cone-like fruits holding small, winged seeds. The seeds are a food source for a variety of birds. The dark green leaves turn yellow in the fall. Paper Birch grows best in areas where the soil is shaded, cool, and moist. Keep the root system moist by using mulch and watering during dry weather. This tree can be short-lived in New Jersey. It does not tolerate heat and humidity well, and grows best in areas with cool summers. Under the proper growing conditions, Paper Birch is an excellent specimen tree. It can also be used in woodland gardens.
River Birch is a large deciduous tree with pinkish-brown, peeling bark, which provides year-round ornamental interest. The dark green, diamond-shaped leaves turn yellow in the fall. It prefers moist to wet soils, and tolerates periodic flooding. An adaptable tree, it will also grow in drier soils. Give this large tree with an extensive root system room to grow! Use River Birch as a specimen tree, or plant it in wet areas, such as rain gardens or along edges of ponds or streams.
Hazel Alder is a fast-growing, deciduous shrub with a tendency to form thickets. It is monoecious (separate male and female flowers appear on the same plant). The greenish male catkins and reddish female catkins bloom March-April. The female catkins are followed by woody, cone-like structures containing the seeds; the “cones” turn a maroon color in fall and persist into winter. A variety of bird species eat the seeds. Fall foliage is yellow-orange. It prefers moist to wet soils, and is flood-tolerant. It grows naturally along stream banks and swampy areas. Alder is a nitrogen-fixing species, adding nutrients to the soil. For these reasons, Hazel Alder is planted as a pioneer species for revegetating disturbed areas along streams or ponds. It can also be used in mass plantings for erosion control or to restore wetlands.
Sugar Maple is a slow-growing, medium-sized deciduous tree that can tolerate shade. Non-descript, greenish flowers bloom in April, followed by maple fruits (double-winged samaras). The impressive fall foliage offers brilliant yellow and orange colors. This species is the main source of sap for the production of maple syrup. Use as a specimen tree or shade tree in the yard. It is intolerant of road salt and soil compaction, so avoid planting in areas with those challenging conditions.
Striped Maple is a shrubby deciduous tree. Small, greenish-yellow flowers bloom April-May. The leaves turn bright yellow in the fall. The distinctive, striped bark provides ornamental interest, particularly in winter. One of its common names, Whistlewood, originates from the traditional practice of carving whistles from its branches. Use in woodland gardens or shady areas of the yard.
