Tree Carya × nussbaumeri [Hican] This tree is a hybrid of the pecan and shellbark hickory, thus the common name of "Hican". It was developed to produce a nut with the taste of pecans, but with the weaker shell of the shellbark hickory. This plant has a large tap root and can be difficult to transplant. Dropped fruits, stems, and leaves can be a litter problem. Can be prone to various fungal leaf spots.
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 Catalpa bignonioides 'Aurea' [Golden Southern Catalpa] The Golden Southern Catalpa can tolerate full sun, but does best in part sun to part shade. This species is weak wooded and should not be placed where it is open to wind and storm damage. 'Aurea' is known for its rich yellow leaf coloration and its broad form. Its flowers are trumpet shaped and white with yellow and purple spots.
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.
Liana (Climbing Vine) Indiana Native Celastrus scandens [American Bittersweet] Sun to partial shade (best flowers in full sun), and tolerant of soil conditions (except wet). Tends to be invasive. Birds are fond of fruits. Tends toward dioeciousness. Female plants need a male pollinator to produce more abundant fruits. Can girdle trees it grows on. Euonymus scale and two-marked treehoppers can cause damage.
Tree Celtis occidentalis 'Chicagoland' [Chicagoland Hackberry] Develops a single upright leader, a 15-year-old tree was 26' high and 14' wide, a chance seedling selected by Roy Klehm, South Barrington, IL.
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 Indiana Native Cercis canadensis [Eastern Redbud] A fine small tree that grows wild in many parts of Indiana. 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. Due to genetic variability, be sure of seed source. Long tap root means that older plants transplant poorly.
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.
Tree Chionanthus virginicus [White Fringetree] Dioecious with male plants showier in flower than females; plant a female if fruits are desired. Plants of known sex are not usually available unless selected in the flowering size. One of the last plants to leaf out in the spring.
