Tree Indiana Native Quercus stellata [Post Oak] A tough find in Indiana and mostly encountered in the wild throughout the southern states, the native Post Oak can be found in oak-hickory forests of southern Indiana. Open grown trees have a dense, round-topped crown with spreading branches for shade. Bark is similar to the White Oak, gray-brown in color with flat ridges, somewhat scaly, eventually ridged and furrowed. Fall color can vary, ranging from deep red to a golden brown.
Tree Indiana Native Quercus velutina [Black Oak] Quercus velutina is a large, deciduous oak with an irregular canopy. It is closely related to Q. rubra (Red Oak), which it is known to hybridize with. The interesting bark of the Q. velutina is nearly black and furrowed. Transplanting is made difficult by the long tap root. Not generally sold commercially.
Shrub Indiana Native Rhus aromatica [Fragrant Sumac] A highly variable species in both ultimate height and fall foliage color. Color probably also varies with soil type, possibly as a function of moisture content. Plants are native to dry, sandy, and rocky soils, and usually color well under these conditions. Useful for bank stabilization since it develops roots on stems touching the soil. It also suckers. Can spread too quickly for some sites (spreading rhizomes). Shear to ground to rejuvenate (try a brush-hog).
Shrub/Tree Indiana Native Salix humilis [Prairie Willow] Prairie Willow is more drought tolerant than other willows. Rabbits and deer eat the twigs. The nectar is used by bees to provide high quality honey.
Tree Indiana Native Salix nigra [Black Willow] The Black Willow is a fast-growing, wet soils tolerant tree, reaching 30 to 60 feet at maturity. Can sucker profusely, so use sparingly in the landscape. In the wild, you can find Salix nigra near floodplains, streams and rivers, and marshes. The ancient Greeks knew the therapeutic values of willow (Salix) and brewed tea made from willow bark to relieve stiff joints and other bodily aches and pains. A number of insect species attack the…
Tree Indiana Native Sassafras albidum [Common Sassafras] Roots sucker and form thickets, which may or may not be desirable. Sassafras tea contains safrole, a mild carcinogen banned in food products. Iron chlorosis in high pH can turn leaves yellow.
Shrub Indiana Native Staphylea trifolia [American Bladdernut] An upright, heavily branched, suckering shrub; sometimes wide-spreading, as a small tree. Used in naturalizing; best reserved for parks and other low maintenance areas; rather nice for foliage effect.
Shrub Syringa meyeri 'Palibin' [Dwarf Meyer Lilac] Flowers by the time it reaches one foot tall, very floriferous. Flowers in spring before leaves are fully out. Powdery mildew resistant. Very low maintenance. Flowers can be damaged by a late spring freeze. Best to prune immediately after flowering to promote flower buds for the next year.
Tree Indiana Native Taxodium distichum [Common Baldcypress] Nice planted in groupings around water. Develops cypress knees (possibly for gas exchange), but generally only near water.
Tree Indiana Native Ulmus rubra [Slippery Elm] The Slippery Elm has a vase-shaped form, similar to that of the American Elm (Ulmus americana), but with more ascending branchlets. This tree gained its common name from the moist, slippery, red inner bark chewed by Native Americans and pioneers to quench thirst. Not considered very ornamental for the landscape, due to its coarse texture, weedy tendencies, and susceptibility to Dutch Elm Disease (although not as severe as the American Elm).
