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 illinoinensis [Pecan] The Pecan is a tall, straight-trunked tree and is the largest of the hickories. It is well-known for its sweet, edible nuts and because of this, it is an important horticultural crop in the south, where it produces fruit most abundantly. However, it is not generally recommended for use in the landscape, due to its pest susceptibility and litter problem. With its large taproot, it can also be quite difficult to transplant.
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.
Shrub Caryopteris × clandonensis [Bluebeard] Is often killed to ground in winter, returning to flower in the same year. Functions much like an herbaceous perennial, primarily for flowering interest, blooming on new growth. This hybrid is much hardier than C. incana and much more showy than C. mongholica. 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…
Shrub Caryopteris × clandonensis 'Blue Mist' [Blue Mist Bluebeard] This cultivar blooms in clusters during late summer with vibrant blue flowers. Is often killed to ground in winter, returning to flower in the same year. Functions much like an herbaceous perennial, primarily for flowering interest, blooming on new growth. This hybrid is much hardier than C. incana and much more showy than C. mongholica. Attractive to bees, butterflies, and hummingbirds. Occasionally kills out completely at the northern edge of its useful range, with tops…
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.
Shrub Indiana Native Ceanothus americanus [New Jersey Tea] New Jersey Tea is a native prairie plant that has thick, deep-reaching, red roots (which can even grow up to 8" in diameter), making it very drought tolerant, but also difficult to transplant. This small, compact shrub is able to fix atmospheric nitrogen and is quite adaptable, not only tolerating drought, but different soil types as well. It is even capable of growing in sandy and rocky soils. The leaves of New Jersey Tea were…
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…
