The American Hornbeam is a small native hardwood tree in the beech family. American Hornbeams grow well in shade and have an interesting bark texture.
The Serviceberry is a small tree which grows well in zones two through eight.
The Redbud is a native tree which grows well in zones four through nine.
The Lacebark Elm (Chinese Elm) is my number one choice for a medium sized plot. This deciduous tree grows 30-60 ft tall and equally wide- is hardy: tolerates salt, sand, air pollution, damage to branches in urban settings, and drought and heat (zones 4-9). A very pretty tree, the Lacebark elm has interesting and colorful bark texture year round as well as iconic Elm leaves (figure 1). There are several varieties all of which are unaffected by the Dutch Elm disease (no spraying required, more resistant than the Zelkova Elm).

The Pagoda tree is originates from Japan. It is a long lived tree with bean-like fruit. New Haven plants them as shade trees and there is one on the Yale Nature Walk. Pagoda trees reach fifty to seventy five feet tall and is categorized by the Urban Resource Initiative as a medium sized tree (figure 2).

The Blackgum (Tupelo) is long lived, native, grows well in zones three through nine, and has a tap root. The Blackgum’s fruit supports many animal species and the tree itself is a habitat for birds.
Giant Sequoia: the largest tree on earth. It’s native range is exclusively in small groves in the Western United states, but careful seed collection and cultivation has lead to individual specimens all over the globe (figure 2). Needle Evergreen tree through zone 8.

Dawn Redwoods are extremely easy and low maintenance trees to grow. They work well for shade, wind, and noise screening (figure 3).

The ginkgo (figure 4) is the only tree with fan shaped leaves and is extremely drought tolerant. The leaves turn yellow in Autumn and can be stepped for tea. Male ginkgo fruit is a round seed pod similar to the Sycamore and London Plane trees. Ginkgos live a very long time and have a recognisable bark pattern.

The Bald Cypress is a distant relative to the Redwood (figure 6) and native to the East coast. It is a deciduous conifer with pyramidal shape. The main differences from the Redwood are that Balding Cyprus reach one hundred twenty feet verses one hundred sixty feet or more. Bald Cypress have alternating groups of needles which are .75in in length. Zones 4-9 great for wildlife too.

The sweetgum is a native tree with star shaped leaves and develops seeds in spiky round pods (figure 7).
Figure 7. Sweetgum leaves and pods.
The Burr Oak is my number one choice for a large deciduous tree because it is extremely heat and drought resistant (figure 8). Burr Oaks can grow up to eighty feet tall and produce the largest acorns of any oak species. Burr Oaks are now being planted in New Haven as street trees through the Urban Resource Initiative.

The White Oak is the state tree of Connecticut and the premier hardwood which was used in boat building. Bark of the white oak is a light gray color and the leaves have rounded edges. White Oaks are also very drought resistant through hardiness zone 9; the native range encompasses the entire east coast figure 9.

The Red Oak is another native oak species to the East Coast (figure 10). Southern Red Oaks have a slightly larger range into zones 9 and 10.

The Atlas cedar, native to Morocco but is planted worldwide as a tree in ornamental landscapes (figure 11). An evergreen, the blue-green needles add distinctive color to outdoor spaces year round. Zones six through nine.

The Eastern White Pine can grow to eighty feet tall in zones three through eight (figure 1).
Figure . Eastern white pines reach an impressive height and branch all around the trunk.
The Southern Magnolia is an evergreen with glossy leaves (Figure ).
