Tree Indiana Native Crataegus mollis [Downy Hawthorn] Quite susceptible to cedar-hawthorn rust, with leaves heavily spotted with orange in some years. Rust limits usage in many areas. Large fruit pose a maintenance issue when they drop.
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 Crataegus × lavalleei [Lavalle Hawthorn] The Lavalle Hawthorn is a small, rounded tree that resulted from a cross of Crataegus mexicana and C. crusgalli. Quite resistant to rust and less thorny than its Cockspur Hawthorn parent.
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.
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…
Shrub/Tree Indiana Native Euonymus atropurpureus [Eastern Wahoo] The Easter Wahoo is an Indiana native shrub/small tree that can be found in open woods or along forest edges and is grown for its attractive red fruits and great fall color. Due to its irregular habit, the Eastern Wahoo can be an issue in the formal landscape, but regular pruning can fix this issue. Far less invasive than the infamous Euonymus alatus (Winged Euonymus or Burning Bush). Flowers are small, rich purple that bloom…
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…
