Tree Magnolia grandiflora [Southern Magnolia] A majestic, upright, heavily branched tree and a favorite in the south. Can get scale and bacterial leaf spot. Leaves fall but never seem to decompose. Fruits can be a little messy. Takes 15 to 20 years from seed to flower. Mostly seed propagated so morphological variability between seed grown plants is great.
Tree Indiana Native Magnolia tripetala [Umbrella Magnolia] Full sun or light partial shade. Tropical appearance. Flowers are creamy white with an unpleasant smell. The cone-like rosy red fruit matures in September-October. Endangered in Indiana. Large leaves can be injured by hail or wind. Perhaps too coarse for most landscape situations.
Tree Micromeles alnifolia [Korean Mountainash] Sorbus alnifolia is an attractive small, dense tree that produces beautiful clusters of white flowers in the spring. In the wild, this plant lives in cooler, mountain climates and is not well-adapted to USDA zone 8 and south. Intolerant of city conditions. Tends to flowers heavier every other year. Susceptible to fireblight and scab, but resistant to borers that frequently attack other Sorbus. Although this plant is commonly referred to as a "mountainash", it is…
Tree InvasiveThis plant is considered invasive Morus alba [White Mulberry] It will grow in nearly any situation. There are occasional problems with cankers, mites, and bacterial blights. Morus alba is very similar to the native red mulberry (Morus rubra), but may be distinguished by the leaves. Its leaves have glossy surfaces whereas the leaves of Morus rubra do not. Morus alba is found throughout the United States, where it invades old fields, urban lots, roadsides, forest edges, and other disturbed areas. It poses an ecological…
Tree Indiana Native Nyssa sylvatica [Black Gum] Especially useful in wet soils. One of the most beautiful of trees, with habit comparable to Quercus palustris, but usually more irregular, and with a greater number of more slender main limbs. Silvery-gray, picturesque branching; strong horizontal accent. Difficult to transplant due to taproot; use container-grown plants when possible, or at least plants dug with a soil ball. Shelter from wind. In the North, select native northern stock as the species has a wide geographic…
Tree Indiana Native Nyssa sylvatica 'Wildfire' [Wildfire Blackgum] Especially useful in wet soils. One of the most beautiful trees, with habit comparable to Quercus palustris, but usually more irregular, and with a greater number of more slender main limbs. Silvery-grey, picturesque branching; strong horizontal accent. Difficult to transplant due to taproot; use container-grown plants when possible, or at least plants dug with a soil ball. Shelter from wind. In the North, select native northern stock as the species has a wide geographic range.…
Tree Indiana Native Ostrya virginiana [American Hophornbeam] A good, trouble-free small shade tree worthy of greater use. Very graceful with many drooping branches that create a rounded habit. Best on drier slopes, and is usually found in native ecosystems. Slow growing, and difficult to transplant. Does not tolerate periodic flooding (as does Carpinus caroliniana) or salt.
Tree InvasiveThis plant is considered invasive Phellodendron amurense [Amur Corktree] A striking tree for its interesting bark and massive framework. Widely adaptable to soil, trouble-free, and drought and pollution resistance. Easily transplanted. May be less hardy when young and rapidly growing. Fruits smell like turpentine when crushed (or stepped on). This tree is demonstrating invasive characteristics in suburban and urban fringe forests. It escapes intended plantings to invade and displace native hardwood forests. Note: only female plants have the potential to become invasive. Phellodendron amurense…
Tree Platanus × acerifolia [London Planetree] Platanus x acerifolia is quite similar to P. occidentalis, but was originally advertised as being much more pest resistant. P. x acerifolia was quickly overplanted, and it is clear that pest resistance varies among hybrids, and can be quite poor. Pests that can severely affect this species include sycamore anthracnose, cankerstain, Botryosphaeria canker, leaf spot, powdery mildew, sycamore lace bug, and American plum borer. One of the largest of shade trees, making massive, majestic specimens.…
Tree Indiana Native Platanus occidentalis [American Sycamore] One of the largest of shade trees, making massive, majestic specimens. Tolerant of urban conditions, but generally found in riparian areas in the wild. The mottled, multi-colored, exfoliating bark is very beautiful and makes for excellent winter interest. Needs a large volume of soil space. Anthracnose leaf and twig blight occasionally disfigure this tree, and can damage it severely. Leaves, twigs, bark, and fruit contribute to a significant litter problem. Although this species can tolerate…
