Shrub Indiana Native Dasiphora fruticosa [Bush Cinquefoil] Extreme hardiness and long season of bloom make this a favorite in severe climates. Low stature and tolerance of poor, dry soils give it added usefulness in other areas also. Can develop a ragged, unkept habit over time. Remove 1/3 of canes each year (3-year pruning cycle), and consider renewal pruning to a very low framework every 3-5 years if needed.
Tree Indiana Native Diospyros virginiana [Common Persimmon] Most are usually dioecious and have a deep tap root which makes large plants difficult to transplant. Flowers attract bees while the 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.
Shrub Indiana Native Dirca palustris [Leatherwood] Dirca palustris is a small, dense, quite rounded, Indiana native shrub with excellent yellow fall coloration. Although it is generally uncommon in the wild, Leatherwood can be found growing naturally and thriving along the ravines of Turkey Run State Park in Marshall, IN. This plant requires rich, moist, acidic soils and should be protected from intense sun. Leatherwood fruits, bark, and roots are poisonous.
Shrub Indiana Native Euonymus americanus [American Euonymus] The American Euonymus is a small, suckering shrub that is native to the eastern portions for the United States, west to Texas. Normally, the American Euonymus can be found in woodlands and can tolerate deep shade and a wide range of soil types. Its flowers are unsual for Euonymus because of its five-petaled flowers instead of the usual four for most other euonymus species. Other common names, such as Strawberry-bush or Hearts-a-Burstin, are derived from…
Tree Indiana Native Fagus grandifolia [American Beech] In a proper site, an excellent trouble-free shade tree with year-round interest. Less adaptable to hot, dry conditions than the exotic F. sylvatica, but somewhat more cold hardy. F. grandifolia is preferred in Zone 4. Like F. sylvatica, this tree is so shallow rooted and casts such heavy shade that grass does not grow well beneath it. Low branching habit is a concern for use in the tree lawn as a street tree (may require…
Shrub/Tree Indiana Native Frangula caroliniana [Carolina Buckthorn] Handsome shrub or small tree with dark green, 8 to 10 vein-paired leaves. Fruits are 1/3" diameter, globose and has a sweet taste to it. Changes from red to black as it matures. Fruit ripes (Red) in August and remain on the plant until October or later, by which time it turns black.
Tree Indiana Native Fraxinus americana [White Ash] Not as adaptable as Green Ash but has better esthetics. Heavy crops of seeds on female trees cause litter, and these germinate freely making the tree slightly weedy. An unattractive ash flower gall (caused by mites) can develop on male flowers and persist into winter. Subject to storm damage, so plant in areas that shelter the tree from strong winds. Emerald Ash Borer is severely affecting all species of this genus. Damage can be prevented…
Tree Indiana Native Fraxinus quadrangulata [Blue Ash] The Blue Ash earned its common name from the blue dye made by early Americans from the inner bark, which contains a substance that turns blue with exposure to air. This tree is naturally found upland in dry, rocky limestone areas and is very drought tolerant. As with all ashes, Fraxinus quadrangulata is extremely susceptible to the Emerald Ash Borer. Damage from this pest can be prevented with the soil drench method imidacloprid, but the…
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.
