Tree Indiana Native Carya glabra [Pignut Hickory] With its straight trunk and strong, hard wood, the Pignut Hickory is most commonly grown for the lumber industry and is not generally used as an ornamental tree. In the wild, it tends to grow on ridges and hillsides in dry to moist soils. This large tree needs a great deal of room to grow and transplants poorly due to its large taproot. The nuts are generally too bitter for humans to eat, but are…
Tree Indiana Native Carya ovata [Shagbark Hickory] The bark of Carya ovata gives the tree its common name and is characteristically rough and shaggy on mature trees, growing in long flat plates, making especially good winter interest. The wood of this tree is especially hard, making it useful for a variety of products. This tree develops a large taproot, making it difficult to transplant.
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.

Prefers full sun but tolerates partial shade. Attractive plant to bees, butterflies, and hummingbirds. Occasionally kills out completely at the northern edge of its useful range, with tops regularly killed back to…

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 Cedrus atlantica 'Glauca Pendula' [Weeping Blue Atlas Cedar] Cedrus atlantica 'Glauca Pendula' is an interesting and beautiful plant with distinctly blue foliage. The habit of this weeping cultivar is determined by training. If left alone and unsupported, the central leader will weep gracefully downwards, but the central leader can also be staked to create a more upright form with cascading branches coming from a straight trunk. Either method produces a quality specimen plant for the landscape. This plant should be moved balled and…
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…
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…
