Shrub Cotoneaster horizontalis [Rockspray Cotoneaster] C. horizontalis is a low, flat, dense shrub with horizontally spreading branches creating a tiered effect. A generally trouble-free cotoneaster, although can be subject to the troubles of Rosaceous plants on occasion. Fireblight is more problematic for this species in the South.
Tree Indiana Native Crataegus phaenopyrum [Washington Hawthorn] One of the finest small trees for winter color. The 1-3" thorns can be dangerous, especially around children. Fireblight, leaf spot, and cedar-hawthorn rust are among the worst problems, although more trouble-free than many hawthorns. Japanese beetles like to feed on hawthorns.
Tree Indiana Native Crataegus viridis [Green Hawthorn] An attractive small tree with beautiful white flower corymbs and bright red persistent fruits. Very adaptable, although leaves are often badly infected by rust so that the entire plant appears to be suffering from the measles.
Tree Crataegus viridis 'Winter King' [Winter King Green Hawthorn] An attractive, nearly thornless vase-shaped small tree with beautiful white flower corymbs and large, bright red persistent fruits. This cultivar was discovered in a fence row by Bob Simpson in Vincennes, Indiana. Very adaptable, although leaves are often badly infected by rust so that the entire plant appears to be suffering from the measles.
Tree Diospyros virginiana 'Meader' [Meader Persimmon] Most usually dioecious. Flowers attract bees. Fruit attracts birds and many mammals. The fruit is astringent when green, sweet and edible when ripe. Fruits, twigs, and leaves can be a littler problem. Deep tap root makes large plants difficult to transplant. Can be poisonous to horses. ‘Meader’ is a self-fertile cultivar usually producing fruit after 2-3 years.
Tree Ginkgo biloba [Ginkgo] The Ginkgo is a long-lived deciduous conifer and gymnosperm. It is frequently termed a "living fossil," as it is the only surviving member of a group of ancient plants with fossils dating back to 270 million years ago. This plant is dioecious, and the so-called fruits (which are actually naked seeds with a soft seed coat) are borne on female trees, are green or tan-orange, and have an offensive odor when ripe and decaying.

Tree Ginkgo biloba 'Autumn Gold' [Autumn Gold Ginkgo] The Ginkgo is a long-lived deciduous conifer and gymnosperm. It is frequently termed a "living fossil," as it is the only surviving member of a group of ancient plants with fossils dating back to 270 million years ago. 'Autumn Gold' is an all male, and therefore, fruitless cultivar that has outstanding golden yellow foliage in the fall. Picturesque, open branches.
Tree Ginkgo biloba 'Magyar' [Magyar Ginkgo] The Ginkgo is a long-lived deciduous conifer and gymnosperm. It is frequently termed a "living fossil," as it is the only surviving member of a group of ancient plants with fossils dating back to 270 million years ago.

Tree Ginkgo biloba 'PNI 2720' [sold as Princeton Sentry®] [Princeton Sentry Ginkgo] The Ginkgo is a long-lived deciduous conifer and gymnosperm. It is frequently termed a "living fossil," as it is the only surviving member of a group of ancient plants with fossils dating back to 270 million years ago. The Princeton Sentry Ginkgo is an all male, and therefore, fruitless cultivar that has a nearly colomnuar, narrow, upright habit.
Tree Indiana Native Gymnocladus dioicus [Kentucky Coffeetree] Gymnocladus dioicus is a large deciduous tree with strong winter character from the branches and bark. Drops pods (female trees) and twigs, frequently causing litter problem, thus eliminating the straight species as a good street tree. Seeds were once used by US settlers as a coffee substitute, however pulp and seeds are toxic when not properly and completely roasted.
