Boxelder maple (Acer negundo) is a fast growing, wide spreading, short-stemmed tree of irregular shape. Under favorable conditions, it can grow 50 to 80 feet with a diameter of 24 inches. It is often planted for shade and ornamental purposes because of its rapid growth. Boxelder maples have compound leaves with three to five leaflets, growing 2-4 inches long and 1-2 inches wide. Like other maples, Boxelder maples have winged seeds, but they are one of the only maples to have drooping clusters of seeds. The twigs are green to purplish, covered at first with a bluish white bloom and later becoming smooth and shiny. The bark is finely ridged, grayish to dark brown, with the occasional greenish tinge.
Silver Maple (Acer saccharinum) are incredibly fast-growing trees with opposite, simple, palmately lobed leaves. The leaves are bright green with a silvery white lower surface that gives the tree a “silvery” appearance from a distance in gentle breezes. The five leaf lobes are often very deep with toothed leaf margins. Silver maples have red to dark reddish purple buds, tiny red flowers often hidden by bud scales, and reddish fruit. The bark of a young tree is smooth and light gray before it separates into irregular rows of long, scaly, ashy colored plates as the tree matures. It is often found in bottomland forests, stream banks, and floodplains, but is tolerant of a wide range of conditions. Silver maples range from green-yellow to yellow to brown in the fall.
White mulberry (Morus alba) is a fast-growing, short-lived tree native to northern China (where it was used to feed silkworms) and naturalized in the Americas. It has been used for several ailments in traditional medicine, including the treatment of prematurely gray hair. White mulberry is also a popular tea. Its young leaves are deeply lobed while mature leaves are simple. Its mature leaves are often confused with the native Red mulberry, and its young leaves are confused with Sassafras. Mulberries in temperate climates are deciduous, while mulberries in tropical climates are evergreen. White mulberries are especially unique because their pollen is released at half the speed of sound.
