Canopy tree replenishment program
Northern Red Oak
Quercus rubra
New Jersey’s state tree, red oaks have straight trunks clear of branches leading to a rounded crown and a canopy that is usually 3/4 as wide as the height. Its leaves turn crimson, golden orange and russet in the fall. Its wood outsells all other hardwoods and is used for multiple purposes. Hosts: over 500 species of butterflies, larval host to Grey Hairstreak Attracts: birds, small mammals and deer Growth: 75-100’h, moist to dry well drained loamy soil, shade tolerant Location: Next to circuit drive as you enter/leave via Bellevue, in the field near the bandstand
Scarlet Oak
Quercus Coccinea
Scarlet oaks are known for their brilliantly colored fall foliage. The branches are thick and ascending; twigs are are smooth and reddish brown. It forms a rounded crown that is somewhat pyramidal. The bark is very thin with fine fissures and scaly ridges. Plant it where there is sufficient space for it to grow upward and spread. Hosts: over 500 species of butterflies Attracts: birds, small mammals and deer Growth: 75’h, dry well drained soil, full sun Location: Next to circuit drive as you enter/leave via Bellevue
Pin Oak
Quercus palustris
These oaks are easy to identify by a pyramidal shape, with a tall straight trunk and slender branches which angle downward on the lower third of the tree. It has a graceful slender appearance. They are named pin oaks because of their very slender angular pin-like twigs. Glossy dark green leaves become deep red in the fall. In my view, in the winter its architecture is a stand out. Hosts: over 500 species of butterflies, larval host to Grey Hairstreak Attracts: birds, butterflies, hummingbirds Growth: 60-70’ h, heavy, poorly drained soils, sun Location: Next to circuit drive as you enter/leave via Bellevue
Swamp White Oak
Quercus bicolor
Swamp White Oak Quercus bicolor
Swamp White Oaks are natives and have attractive peeling bark which is especially apparent on young trees. The leaves are dark green on top with a silvery underside, and the acorns are distinguished by their long stalks. Every 3 to 5 years they produce large “mast” crops of acorns, this reduces seed predation and improves reproduction. This is a “keystone tree” as it supports many types of wildlife from insects to butterflies to birds and mammals.
Hosts: over 500 different species of butterflies/moths
Growth: 50-60’ h, moist to wet acidic soil, adapts to dry site
Location: Next to Circuit Dr between triangle and dog park, on circuit drive heading to leave to Watchung
Willow Oak
Quercus phellow
Willow Oak Quercus phellos
A popular landscape tree this has a fast growing nature, balanced round form and fine texture. It is tolerant of pollution, transplants well and adapts to most soil conditions. Like most oaks, it is also a high value tree for wildlife supporting birds, mammals and butterflies. The smooth edged narrow leaves are hairy on the bottom and golden in the fall and the bark gets dark grey and furrowed as it ages. Acorns are eaten by woodpeckers, songbirds, ducks, small mammals, wild turkeys, deer and bears; they are edible for humans only if boiled. Hosts: Imperial moth, butterflies - banded hairstreak, Edward’s hairstreak, gray hairstreak, white hairstreak, Horace’s duskywing, Juvenalis dustywing Attracts: birds, mammals and butterflies Growth: 40-75’ tall, 25-50’ wide, most soils, full sun/part shade Location: Upper Circuit drive, between beeches and yellowwoods, and opposite dog park entrance

Cercis canadensis (assorted varieties appear in the park)
A member of the pea family, this produces glorious pink/purple flowers on the bark of its stems. Its short stature and flat or slightly rounded crown means it is frequently found growing under taller trees in the wild. Its heart shaped leaves are a cool note of color in the summer and turn assorted red, yellow and orange shades in the fall depending upon the variety of tree. In drought, regular watering is needed to keep this tree healthy. Native Americans used the bark for medicinal purposes and the flowers are edible and taste like peas.

Dogwood
Cornus florida ‘Appalachian spring’
An understory tree topping out at a maximum 25 ft tall this tree grows from Canada through the eastern US to eastern Mexico. It can be a bit tricky to get established if its light/soil needs are not met but is well worth the effort in terms of its beauty. The showy flower is actually a collection of tiny flowers surrounded by 4 petal like showy bracts. They are followed by red fruits which feed songbirds and wildlife through the fall and winter. Native Americans used the dogwood for medicinal purposes, carving wood and disinfectant. Its strong wood is used for tool handles and weaving shuttles.

American Holly
Ilex opaca
Both male and female plants are required to produce berries. This tree grows slowly into a pyramidal shape that has limbs all the way down to the ground. The leaves and fruits make beautiful colors in the winter garden, and branches are often used for Christmas decor. Read up this tree and make sure that its a fit for a planting location as it becomes large, it’s highly flammable and while fairly adaptable, it has a few specific dislikes re soil, drainage and amount of shade.

Sweet Bay Magnolia
Magnolia virginiana
This slender magnolia smells best in the early evening and blooms sporadically in the summer month with white cup shaped flowers that open in the morning and close in the evening. Cone like fruits with bright red seeds provide fall interest. In the south it becomes a tall tree but in our area it is usually a multi stemmed open shrub. While its flowers are far smaller than the glossy leaved southern magnolia, its long blooming period, accessible height and lovely fragrance makes it a great addition to a home garden.
Hosts: spicebush swallowtail larvae, eastern tiger swallowtail larvae Attracts: deer, birds and small mammals
Growth: 10-35’tall, 10-35’wide, full sun/part shade, acid soil
Bloom: late spring through summer
Location: Lower circuit drive in the open area next to toe stretch and in a patch around the curve towards Bellevue
Bald Cypress
Taxodium distichum
These will reach a height of 50 to 70 feet tall. One of the longest living trees in the world it has an average lifespan of 600 years. We planted it as a specimen tree to help frame the beauty of our open fields. It’s also a great example of planting for a warming climate because this tree is more prevalent further south but, as average temperatures climb, it will do very well here. Unlike other cone bearing trees it “goes bald” loosing its needles annually. In fall this is a showstopper turning a gorgeous russet red.
Attracts: birds and mammals eat the seeds
Growth: 50-70’ tall, 20-30’ wide, full sun/part shade, most acid soils
Bloom: Spring
Location: In the field by the band stand
