Shrub InvasiveThis plant is considered invasive Berberis thunbergii var. atropurpurea 'Crimson Pygmy' [Red Dwarf Japanese Barberry] The Red Dwarf Japanese Barberry is exceedingly popular due to its dense, low growing form, brilliant foliage, and tolerance to tough urban conditions. For the best leaf coloration, place in full sun. This plant tolerates dry soils, but will suffer in wet, poorly drained soils.
Tree Betula papyrifera 'Renci' [sold as Renaissance Reflection®] [Renaissance Reflection Paper Birch] Betula papyrifera 'Renci' is faster growing and more heat resistant than the straight species. This tree requires full sun and is not suitable for poor or polluted city conditions.
Tree Indiana Native Betula populifolia [Gray Birch] Beautiful white bark, although becomes dirty gray with age. Does well on the poorest of sterile soils, seeds, and suckers quickly. Grows on sandy, rocky and even gravelly sites. Tolerates both wet and dry conditions. Prefers full sun. Susceptible to leaf miner and cankers; more resistant to the bronze birch borer. Leaf minors especially problematic.
Tree Carpinus betulus 'Columnaris' [Columnar European Hornbeam] Carpinus betulus is relatively trouble-free and tolerates a wide range of soil conditions and some shade. This plant is also very tolerant of heavy pruning, making it useful as a hedge. The cultivar 'Columnaris' is a narrow, columnar cultivar that is slow-growing with densely set branches and leaves.
Tree Castanea mollissima [Chinese Chestnut] Overall tough and durable, but can be susceptible to blight, twig canker, and orient chestnut wasp. Also susceptible to weevils, which damages the roots. Prefers well-drained, loamy soils, full sun, and hot, arid conditions.
Tree Indiana Native Catalpa speciosa [Northern Catalpa] Coarse winter trunks and branches are bold and striking; picturesque. Best for difficult areas. Wood is rot resistant, but is somewhat brittle so branches can fall in wind and ice storms. Too coarse of texture for most urban landscapes. Short-lived to about 50 years.
Tree Cercidiphyllum japonicum [Katsuratree] More hardy once established than when young. A striking specimen tree, useful for partial shade and accent. Unusually free of insect problems. Leafs out early in spring. Forms multiple trunks unless pruned. Does not transplant well. Not very drought-tolerant, particularly after transplanting.
Tree Cercis canadensis 'Forest Pansy' [Purple-Leaf Eastern Redbud] 'Forest Pansy' is a unique and attractive cultivar that has deep purple foliage, which generally fades to a dark, lustrous green in late summer or under drought conditions. Beautiful rose-purple flowers smother the branches in the spring. A fine small tree that is relatively trouble-free and drought-resistant. Requires some protection from the sun in hotter climates, however flowering decreases with deep shade. Canker, leaf spot, and verticillium wilt can be problematic for older trees, or…
Tree Cercis canadensis 'Rubye Atkinson' [Pink Flowering Eastern Redbud] 'Rubye Atkkinson' has strongly pink and slightly smaller flowers, distinctly different from the purplish-pink flowers of the straight species. A fine small tree that is relatively trouble-free and drought-resistant. Requires some protection from the sun in hotter climates, however flowering decreases with deep shade. Canker, leaf spot, and verticillium wilt can be problematic for older trees, or trees weakened by other environmental stresses. Long tap root means that older plants transplant poorly.
Liana (Climbing Vine) InvasiveThis plant is considered invasive Clematis terniflora [Sweetautumn Clematis] Keeping the root system cool by deep soil preparation and mulch around the base is beneficial. Climbs by twining stems and clasping leaves, so needs trellis or wire support. Extremely vigorous; can engulf an entire structure. Prune out old wood, and dead wood that arises from winter-kill.
