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 Morus rubra [Red Mulberry] The Red Mulberry is fairly adaptable and can sometimes be a prolific self-seeder. To prevent bleeding, it should be pruned in late fall or winter. Although somewhat more sensitive to soil requirements, Morus rubra is considered to be a better choice than the related Morus alba (White Mulberry), which has a much more invasive character. Morus rubra is dioecious, so male and female flowers are borne on separate trees. Female trees, if fertilized, bear edible…
Shrub Nandina domestica [Heavenly Bamboo] The beautiful red fruits are so prolific they can even bend down branches. Tolerates full sun or shade, even fruits well in shade. Prune by cutting canes back to ground. Develops iron chlorosis on Southwestern US due to high soil pH. 'Atropurpurea Nana' stays 2' high with reddish-green color throughout summer, turning dark red in winter.
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 Nyssa sylvatica 'Hayman Red' [sold as Red Rage®] [Red Rage Black Gum] 'Haymanred', the broadly pyramidal cultivar of the Indiana native Black Gum, is know for its rich and vibrant fall color, lustrous dark green leaves and resistance to leaf spot. Selected from southern Indiana and introduced by Mike Hayman, it is one of the best cultivars of black gum. Can be difficult to transplant due to its taproot, use container-grown plants or plants dug with a soil ball. Can be used in areas with wet soils.
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.

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 Indiana Native Oxydendrum arboreum [Sourwood] This plant gets it common and scientific name from its sour-tasting leaves. The genus name is derived from the Greek word "oxys", meaning sour, and "dendron", meaning tree. Honey produced from the pollen of Sourwood flowers is considered valuable. The attractive, slightly fragrant flowers are often prolifically produced, especially in full sun, and are effective for up to four weeks. Like all Ericaceous plants, Oxydendrum arboreum requires rich, organic, moist, well-drained, and acidic soil. This…
Tree Parkinsonia × [Hybrid Palo Verde] Semi-evergreen leaves, and smooth line green trunks and branches year round. Palo Verde means "green stick" in Spanish, and the green bark carries on photosynthesis. Survives in the desert on natural rainfall once established. Few problems. Needs some minor clean up maintenance of flowers and leaves. Prune when young to develop multi-stems and show off the beautiful bark. 'Desert Museum' is a V-shaped thornless hybrid having genetic characteristics indicating complex hybridization between three species, Parkinsonia…
