Tree Cedrus libani ssp. stenocoma 'Purdue Hardy' [Cedar of Lebanon] Widely adaptable, the Cedar of Lebanon was considered hardy from Zone 7 southward until hardy strains were imported from higher elevations in Asia Minor, beginning with the Arnold Arboretum expedition in 1903. The Cedar of Lebanon prefers pollution-free, open, and sunny areas. It is difficult to transplant and is not tolerant of air pollution or shade. This tree is also very difficult to propagate from cuttings (i.e. asexually). It is the most cold-hardy of the…
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 Indiana Native Celtis laevigata [Sugar Hackberry] The Sugar Hackberry is very similar to the Common Hackberry (Celtis occidentalis) and is especially useful in large-scale situations with dry soils and heavy winds. This species gained its common name from the juicy, sweet berries it produces. Subject to a leaf nipple gall (caused by psyllid insect Pachypsylla dismamma, one of many jumping plant lice). However, the Sugar Hackberry is more resistant to witches'-broom disease (caused by Eriophyid mite) than the Common Hackberry. Especially…
Tree Indiana Native Celtis occidentalis [Common Hackberry] As well adapted to Midwestern conditions as American Elm, and a reasonably good substitute in form as well. Especially useful in large-scale situations with dry soils and heavy winds. Subject to a leaf nipple gall (caused by psyllid insect Pachypsylla dismamma, one of many jumping plant lice) and witches'-broom disease (caused by Eriophyid mite), both minor in most situations in the Midwest. Especially coarse texture limits use in designed landscapes.
Tree Celtis occidentalis 'Prairie Pride' [Prairie Pride Hackberry] As well adapted to Midwestern conditions as American Elm, and a reasonably good substitute in form as well. Especially useful in large-scale situations with dry soils and heavy winds. 'Prairie Pride' has glossy, thick, leathery leaves and is less of a litter problem than the species type due to its lower fruit production. Subject to a leaf nipple gall (caused by psyllid insect Pachypsylla dismamma, one of many jumping plant lice), but is not subject…
Shrub Indiana Native Cephalanthus occidentalis [Common Buttonbush] Buttonbush is an Indiana native and a wet-soil tolerant shrub found near marshes, wetlands, and river banks. This is a great choice for those wet areas in the landscape or a featured shrub in your rain garden. The flowers of this shrub are globe-like in shape and bloom from June through August, attracting wildlife such as butterflies. The leaves of the Buttonbush emerge late in the Spring and might look dead until mid-May. Though this…
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 'Alba' [White Eastern Redbud] 'Alba' is a white-flowering Eastern Redbud ("Whitebud"). 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 Cercis canadensis 'Appalachian Red' [Appalachian Red Eastern Redbud] 'Appalachian Red' is known for its profusion of intensely bright pink (not quite red) flowers 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 trees weakened by other environmental stresses. Long tap root means that older plants transplant poorly.
