The Swamp White Oak is a medium-sized deciduous tree native to North America. It is commonly found in swamps, lowlands, floodplains, and near streams and lakes. The leaves are two-toned, green on top and silvery-white on the undersides, adding to the visual appeal of this popular shade tree.

In the fall, the Swamp White Oak produces acorns which are an important food source for wildlife. It also provides a habitat for the larvae of many butterfly and moth species, playing an important ecological role. Although its growth is slow in the first few years, once the roots are established, it can achieve faster annual growth.

The Common Hackberry is a medium-sized deciduous tree that resembles the American Elm but is immune to Dutch Elm Disease. They are versatile and can adapt to a variety of growing conditions.

It produces purple-red, berry-like fruit with a large seed in the center. Both the sweet flesh, which tastes similar to dates, and the crunchy seed are edible. The fruit remains on the tree throughout the winter, offering a valuable food source for birds and other wildlife.

The Common Hackberry can also be a great addition to a pollinator garden. The tree itself is a host for the larvae of several butterfly species and the flowers provide a source of pollen and nectar.
