Tree Liquidambar styraciflua 'Rotundiloba' [Rotundiloba American Sweetgum] 'Rotundiloba' has distinctly rounded leaf lobes and is fruitless. This cultivar is also narrower than the species and has variable yellow to burgundy fall color. It is difficult to establish good branching and canopy on young 'Rotundiloba' trees. Widely adapted to soils and climates. Rather difficult to transplant in large sizes. Select northern stock for use in North.
Tree Indiana Native Liquidambar styraciflua (Shuttle Gum Group) [American Sweetgum] This group of Liquidambar styraciflua (Sweetgum) trees was germinated in August of 1984 aboard the space shuttle Discovery. Purdue astronaut Charles Walker of Bedford, Indiana, brought back 200 tiny trees; these recognize Purdue's many astronauts. Sweetgums are handsome shade trees with few troubles and outstanding seasonal interest. Widely adapted to soils and climates, as evidenced by their wide range. Fall foliage coloration varies greatly in timing and intensity among individuals. Rather difficult to transplant in…

This tree, closely related to Cladrastis kentukea (American Yellowwood), is an adaptable plant that is able to fix atmospheric nitrogen.
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…
