Shrub/Tree InvasiveThis plant is considered invasive Elaeagnus angustifolia [Russian-olive] Widely adaptable and invasive plant in the Midwest. Like other members of the family, fixes atmospheric nitrogen. Can be a large shrub or small tree. Spreads by rooting suckers. Especially tolerant of extreme cold and drought, but does not tolerate extreme heat of the south. Verticillium wilt and stem canker may be a problem in some areas. Needs some pruning to keep vigorous and in good form. Berries used to make sherbet in some parts…
Tree Eucalyptus papuana [Ghost Gum] Gained its common name from its beautiful, smooth, white bark. Drought tolerant, low water use once established. Adapted well to urban conditions. The leaves have a high phenolic acid content and make it difficult to grow other plants beneath the Ghost Gum. The eucalyptus beetle poses greatest threat, with oval-shaped holes being one of the signs of infestation.
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 InvasiveThis plant is considered invasive Euonymus alatus 'Compactus' [Dwarf Winged Euonymus] The dense and lower-growing 'Compactus' is one of the most common Winged Euonymus cultivars. 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 Euonymus kiautschovicus [Spreading Euonymus] Foliage fully evergreen in the South, but persists for only about half the winter in the North. Although not as serious as in other species of Euonymus, scale insects can be a problem. May be killed to ground in severe winters, but grows back rapidly.
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…

Tree Fagus sylvatica 'Dawyck' [Upright European Beech] In a proper site, an excellent trouble-free shade tree with year-round interest. More adaptable to hot, dry conditions than our native F. grandifolia, but somewhat less hardy. F. grandifolia is preferred in Zone 4. The cultivar 'Dawyck' is very strongly upright and columnar.
Tree Fagus sylvatica 'Purple Fountain' [Weeping Purple-Leaf European Beech] In a proper site, an excellent trouble-free shade tree with year-round interest. More adaptable to hot, dry conditions than our native F. grandifolia, but somewhat less hardy. F. grandifolia is preferred in Zone 4. 'Purple Fountain' is a somewhat columnar, yet weeping cultivar with long, pendulous braches. Foliage is attractive and emerges deep red-purple, generally fading to a bronzy purple-green by the end of the summer.
Tree Fagus sylvatica 'Purpurea Tricolor' [Tricolor Beech] Purple leaves are striped and edged with rose and pinkish white, more narrow leaves. In a proper site, an excellent trouble-free shade tree with year-round interest. More adaptable to hot, dry conditions than our native F. grandifolia, but somewhat less hardy. F. grandifolia is preferred in Zone 4. Like F. grandifolia, this tree is so shallow rooted and casts such heavy shade that grass does not grow well beneath it. Low branching habit is a…
