The forests throughout most of the state have a luxuriant undergrowth consisting of a great variety of shrubs, flowering plants, grasses, ferns and mosses, and the display of magnolias, azaleas, kalmias, golden rod, asters, jessamines, smilax, ferns and mosses is often one of unusual beauty.
Buttercups, violets, anemones, spring beauties, trilliums, arbutus, orchids, columbine, laurel, honeysuckle, golden rod and asters are common wild flowers, and of ferns there are many varieties.
Nearly all the species of plants which grow on these prairies are common to Europe (paeonics, Hemerocallis, asters, pinks, gentians, violets, Cypripedium, Aquilegia, Delphinium, aconites, irises and so on), but here the plants attain a much greater size; a man standing erect is often hidden by the grasses.
Cowslips, violets, anemones, buttercups and blood-roots are conspicuous in early spring, the white pond lily and the yellow pond lily in summer, asters and golden-rod in autumn, and besides these there are about 1500 other flowering plants in the state and more than 50 species of ferns.
Among indigenous fruit-bearing trees, shrubs and vines the state has the bird cherry, black cherry, blueberry, cranberry, raspberry, blackberry, gooseberry, strawberry, grape and black currant; and conspicuous among a very great variety of shrubs and flowering plants are the rose, dogwood, laurel, sumac, holly, winterberry, trilliums, anemones, arbutuses, violets, azaleas, eglantine, clematis, blue gentians, orange lilies, orchids, asters and golden rod.
