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 'Goldspire' [sold as Ginkgo Goldspire™] [Goldspire Ginkgo] Non-fruiting cultivar of Ginkgo, often thought of as highly ornamental.
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. 'Magyar' is an all male, and therefore, fruitless cultivar that has a narrow, strongly upright habit.
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 Gleditsia triacanthos f. inermis [Thornless Common Honeylocust] This large tree has finely compound leaves that provide a pleasant, dappled shade in the summer. The thornless forma inermis is only sold in commerce, as the profuse thorns of the species type can be a liability. Mimosa webworm and locust mite are serious pests in the Midwest, and are becoming more serious (especially in areas tending toward monoculture). Can be controlled with spraying.
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.
Tree Halesia carolina [Carolina Silverbell] This small tree is interesting in bloom and rather neutral otherwise, but relatively trouble free and useful in many situations as a neutral background plant, or for its flowers. Best grown as a single stem and allowed to branch low (20-30"). Does not transplant well (a particular problem with field-grown plants).
Tree Halesia carolina 'Arnold Pink' [Pink Carolina Silverbell] This small tree is interesting when in bloom with pink bell-shaped flowers that are larger than the straight species, but this plant is rather neutral otherwise. However, it is relatively trouble free and useful in many situations as a neutral background plant, or for its flowers. Best grown as a single stem and allowed to branch low (20-30"). Does not transplant well (a particular problem with field-grown plants).
Shrub/Tree Indiana Native Hamamelis virginiana [Common Witchhazel] Flowers are in evidence because of their spicy fragrance before they are visually obvious, but are fairly showy after leaf drop. Should not be pruned (tip pinching would be acceptable to direct growth).
Tree Heptacodium miconioides [Seven-son Flower] The common name, Seven-Son Flower, is derived from the cluster of 7 small flowers contained within each whorl. The flowers are followed by very showy, reddish fruit structures that have the appearance of flowers. The tan, shredding bark is attractive and exfoliates in long strips to reveal a dark brown inner bark. This plant can be hard to find, both in the wild and in commerce. Needs pruning to maintain aesthetics.
