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…
Tree Indiana Native Liriodendron tulipifera [Tuliptree] Handsome, tall shade tree with strong central leader. Performs best in good soil with adequate moisture. Variable in hardiness, depending on geographic source. Use native stock when possible. State tree of Indiana, Kentucky, North Carolina, and Tennessee. Slightly weak-wooded. Subject to damage in very windy sites. Subject to aphid and scale insects when weakened. Needs good drainage and a lot of soil (tree lawn may be too small). Its poorly branched fleshy root system (taproot)…
Shrub InvasiveThis plant is considered invasive Lonicera maackii [Amur Honeysuckle] Widely adaptable to different soils and exposures. Can be trained into a small patio tree. Suckers freely, requiring pruning in intensive situations. Seeds, carried by birds, germinate freely, and weed seedlings result. High shade tolerance contributes greatly to its highly invasive character. Perhaps the worst woody weed in the Midwestern and Northwestern US.
Tree Indiana Native Magnolia acuminata [Cucumbertree Magnolia] This tree gets it name from the cucumber-looking fruits it bears in the fall. Full sun is best, although it has tolerance for partial shade. Because the roots are thick and fleshy and grow downward more than out, it can be moderately difficult to transplant. Generally trouble-free, but scale can be a problem on occasion. This species may not be ideal for street tree plantings because of a tendency to suffer ice damage.
Tree Magnolia × loebneri 'Encore' [Encore Loebner Magnolia] Encore Loebner Magnolia has a more rounded, compact habit than the hybrid Magnolia x loebneri, reaching 10-12' in height. This cutlivar has anywhere from 18 to 25 tepals that are pink-tinged at the base. Plant in a protected location to prevent spring frosts from damaging the flowers.
Shrub/Tree Magnolia stellata [Star Magnolia] Handsome specimen at all seasons. Needs at least some protection from strong wind in Zones 4 and 5. Somewhat prone to breakage in severe ice storms. Early blooming flowers often destroyed by late spring frosts.
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.
Shrub/Tree Magnolia virginiana [Sweetbay Magnolia] Nice flower fragrance, but never overwhelming. Does well in wet soils, unlike other magnolias. Requires acid soil, some moisture, and tolerates some shade. Chlorosis can sometimes be a problem, especially prevalent on alkaline soils.
Tree Malus × 'Adirondack' [Adirondack Flowering Crabapple] The Flowering Crabapple is a popular small ornamental tree with an extremely showy flower display in the spring. This variant has a vase-shaped (somewhat columnar) habit, extremely upright branching, and high resistance to apple scab, fireblight, cedar-apple rust, and powdery mildew. Tends to flower and fruit in alternate years. Well-drained heavy loam soils and full sun promote best growth.
Tree Malus × 'Indian Magic' [Indian Magic Flowering Crabapple] The Flowering Crabapple is a popular small ornamental tree with an extremely showy flower display in the spring. 'Indian Magic' is not as disease resistant as others, being moderately susceptible to scab. Tends to flower and fruit in alternate years. Well-drained heavy loam soils and full sun promote best growth. Can be susceptible to many pests and diseases, including apple scab, fireblight, Japanese beetles, leaf spot, cedar-apple rust, and powdery mildew. May look ragged at…
