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 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…
Tree Parrotia persica [Persian Parrotia] One of the best trees for foliage and bark effect. Very adaptable, tolerating drought, various soils, heat, cold, etc. Prefers full sun but tolerates light shade. Sites with strong winter winds will surely cause tip dieback in Northern Indiana.
Tree Parrotia persica 'Vanessa' [Vanessa Persian Parrotia] Vanessa is a cultivar that has a distinctly upright or columnar habit. One of the best trees for foliage and bark effect. Very adaptable, tolerating drought, various soils, heat, cold, etc. Prefers full sun but tolerates light shade. Sites with strong winter winds will surely cause tip dieback in Northern Indiana.
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 Picea abies [Norway Spruce] Slight mite susceptibility in hot, dry sites. Some susceptibility to borers. May become thin, open, and have a less attractive habit at maturity.
