Plant advice from The Morton Arboretum: Downy arrowwood is a little known native viburnum that has ornamental characteristics similar to the more commonly planted southern arrowwood (creamy white flowers and red fall color)
Downy hawthorn has the typical white flowers and red fruit of hawthorns, but is not always as thorny as other species. This native tree is beautiful, but is prone to the cedar rust diseases.
Downy serviceberry is a four-season plant offering white flowers in spring, small red berries in summer, excellent fall color and gray bark in winter. The fruit is usually eaten very quickly by birds.
Plant advice from The Morton Arboretum: Dwarf fothergilla is a great multi-season shrub offering white flowers in spring, good gray-green leaves in summer and yellow, orange and red color in autumn.
The eastern arborvitae is an extremely common evergreen tree or shrub, used often as a specimen, in hedges, or for privacy. The small cones open up to look like small flowers and appeal to birds such as cardinals, grosbeaks, and chickadees. There are many cultivars that vary in height and other characteristics. On some varieties, the foliage may discolor in winter.
Eastern cottonwood is a large, fast-growing tree found growing along streams, rivers, and lowland areas. It is native to eastern North America through the Midwest and Chicago region. Due to its large size, weak wood, and penetrating roots, it is best used on large properties away from residential areas.
One of the more shade-tolerant evergreens, the eastern hemlock has many uses as a specimen, sheared as a hedge, or planted for screening. Native to the eastern United States, the hemlock resembles a large Christmas tree with its broadly pyramidal, pendulous branches; fine, dark-green needles; and abundant brown cones that hang from branches like small ornaments.
Eastern red-cedar is native to eastern North America. These cold-hardy, adaptable evergreen trees serve many purposes in the landscape, especially in sites that are dry, alkaline or windy. Because they are quite salt-tolerant, they can be used near roads, driveways, and sidewalks.
Eastern white pine
The Eastern white pine is a tree for landscapes with ample space. Its fine feathery needles, open canopy, and straight trunk get more picturesque with age. Trees are fast-growing and long-lived.
A number of elms are available that can resist the pathogen that causes the devastating Dutch elm disease. Since the disease first began mowing down American elms in the 1930s, scientists and breeders have been developing alternatives. Most of these trees are hybrids that cross various species of American, Asian and European elms. Some are selections of species that were observed to resist the disease. Not all these trees have the characteristic vase- or fountain-shaped arching branch structure of the beloved American elm, but some come close. Some also have resistance to other disease and pests that trouble elms. As time goes on, better cultivars are developed, but some of the older ones may still be on the market.
