Tree Acer palmatum [Japanese Maple] A refined but striking specimen in its several forms, differing in color, texture, and habit, but all graceful. Newly expanded foliage may be damaged by sun and wind. Plant where it will receive some protection from the elements, especially winter elements. Can leaf out early and be killed back by a late freeze. Prefers some shade and good moisture.
Shrub Aronia arbutifolia 'Brilliantissima' [Brilliant Red Chokeberry] The Brilliant Red Chokeberry has dark green leaves that turn a stunning deep red in the fall. 'Brilliant' produces larger and more abundant flowers and a greater number of red berries than the species type. Because birds find the fruits unappealing, the berries are allowed to persist well into the winter months. This plant tends to sucker and create colonies.
Shrub InvasiveThis plant is considered invasive Berberis thunbergii var. atropurpurea 'Crimson Pygmy' [Red Dwarf Japanese Barberry] The Red Dwarf Japanese Barberry is exceedingly popular due to its dense, low growing form, brilliant foliage, and tolerance to tough urban conditions. For the best leaf coloration, place in full sun. This plant tolerates dry soils, but will suffer in wet, poorly drained soils.
Tree Betula papyrifera 'Renci' [sold as Renaissance Reflection®] [Renaissance Reflection Paper Birch] Betula papyrifera 'Renci' is faster growing and more heat resistant than the straight species. This tree requires full sun and is not suitable for poor or polluted city conditions.
Shrub Indiana Native Clethra alnifolia [Summersweet Clethra] Spreads by underground stems to make large clumps, but can be restrained when necessary. Can be badly infested with mites, especially on dry soils. Can suffer in full sun and/or dry soils, but can bloom well in shade.
Shrub/Tree Cornus officinalis [Japanese Cornel Dogwood] The Japanese Cornel Dogwood is a large multi-stemmed shrub or small tree of oval rounded outline, usually branching to the ground. No serious disease problems, although it sometimes suckers abundantly. These suckers should be removed to control spread; this is especially important if maintaining this plant in tree form. Closely related to Cornus mas, but tends to have more attractive bark, is more open in habit, flowers one to two weeks earlier, and is slightly…
Shrub Euonymus fortunei 'Vegetus' [Vegetus Wintercreeper Euonymus] This cultivar has a more shrub-like habit than the species type, but can be moderately effective as a groundcover or wall climber. Also much heavier fruiting than the straight species; the fruiting display can be quite attractive, if fruits are borne in high enough numbers. Very susceptible to Euonymus Scale.
Shrub/Tree Lagerstroemia indica [Common Crapemyrtle] Can be grown as a tree or shrub. This species prefers hot sunny sites. For Zones 5 and 6, apply winter mulch to protect roots. Flower color ranges from white, pink, purple, or deep red that terminates the current year's growth. Long flowering period from July to September. Can have problems with powdery mildew.
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 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.
