Liana (Climbing Vine) Clematis × jackmanii [Jackman's Clematis] The Jackman Clematis is a hybrid that has flowers with large, rich purple sepals, which develop on new growth. The root system should be kept cool by deep soil preparation and mulching around base. It is said that Clematis prefer "a warm top and a cool bottom". While this is generally true, provide some shade during the day to the top portion for best results. Climbs by twining stems and clasping leaves, so needs a…
Liana (Climbing Vine) InvasiveThis plant is considered invasive Clematis terniflora [Sweetautumn Clematis] Keeping the root system cool by deep soil preparation and mulch around the base is beneficial. Climbs by twining stems and clasping leaves, so needs trellis or wire support. Extremely vigorous; can engulf an entire structure. Prune out old wood, and dead wood that arises from winter-kill.
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 Indiana Native Cornus amomum [Silky Dogwood] Easy to transplant. Relatively trouble-free. A three-year pruning cycle improves form, vigor, and winter stem color effect. Cutting all stems 6-12" from ground in late winter has similar effect. Best in mass plantings. Excellent for winter color. Scale and leaf spot can be a problem. Can appear a bit coarse in the landscape.
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 Indiana Native Corylus americana [American Hazelnut] The American Hazelnut is a medium to fast growing shrub and an Indiana native. Being monoecious, the male catkins are 1 1/2 to 3" long, that emerge yellowish brown and are quite showy in early spring. The female catkins are inconspicuous with its stigma and style barely protruding out of the buds, but the color is a rich red. The American Hazelnut is a great large shrub for native restoration projects or adding seasonal interest…
Shrub/Tree Cotinus × 'Grace' [Grace Smokebush] 'Grace' has become a popular cultivar with its purple emerging leaves and giant panicles of smokey, pink flowers. The "flowers" are actually misty fruiting panicles that give the species its name. The fine-textured hairs on the fruit pedicels and peduncles change colors, being best when tinted smoky pink. Can be pruned to low framework each year to promote plant coloration which occurs best on vigorous stems.
Shrub Indiana Native Dasiphora fruticosa [Bush Cinquefoil] Extreme hardiness and long season of bloom make this a favorite in severe climates. Low stature and tolerance of poor, dry soils give it added usefulness in other areas also. Can develop a ragged, unkept habit over time. Remove 1/3 of canes each year (3-year pruning cycle), and consider renewal pruning to a very low framework every 3-5 years if needed.
Tree Indiana Native Diospyros virginiana [Common Persimmon] Most are usually dioecious and have a deep tap root which makes large plants difficult to transplant. Flowers attract bees while the fruit attracts birds and many mammals. The fruit is astringent when green, sweet and edible when ripe. Fruits, twigs, and leaves can be a littler problem.
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.
