Tree Crataegus × mordenensis [Morden Hawthorn] This uncommon plant resulted from a cross between Crataegus laevigata 'Paul's Scarlet' and C. succulenta'. It has attractive clusters of double flowers and is highly resistant to hawthorn rust.
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 × 'Vaughn' [Vaughn Hawthorn] This small tree is a hybrid of Crataegus crusgalli x C. phaenopyrum. It is generally grown for its fragrant clusters of white flowers in the spring and prolifically produced red fruits that persist into winter. Due to its numerous thorns, it is best used in areas with low traffic. Highly susceptible to rust.
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.
Shrub Cycas revoluta [Sago Palm] Unlike what the common name suggests, the Sago Palm is not a true palm, but actually a cycad. Useful for fine planting near entranceway. Not salt tolerant. Scale, leaf spot, micronutrient deficiencies can be problems. The variety variegata has yellow-green leaf variegation patterns.
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.
Tree Eucommia ulmoides [Hardy Rubber Tree] The Hardy Rubber Tree is an adaptable, relatively trouble-free plant that makes for an excellent shade tree. Its sap can be harvested for rubber, but this is an expensive and complex process. The specific epithet (ulmoides) refers to the leaf shape of the Elm genus (Ulmus), which is similar to that of Hardy Rubber Tree leaves. It is the only member of this family. Contains about 3% rubber content on a dry weight basis. It…
Shrub InvasiveThis plant is considered invasive Euonymus alatus [Winged Euonymus] Widely tolerant of most soil and microclimatic conditions, but develops good fall foliage color only when exposed to considerable direct sun. Tolerates heavy pruning. Can be troubled by scale insects, although not so frequently as the evergreen euonymus. Fruits are toxic. Avoid very dry or wet sites. Can be invasive, seeding into woodlots.
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…
