Shrub Cornus sericea 'Flaviramea' [Yellow Twig Redosier Dogwood] 'Flaviramea' has yellow twigs that are especially prominent in winter. High susceptibility to canker. Grows well in a variety of situations, including wet soil. 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. Leaf blights and twig cankers can be problematic.
Shrub/Tree Cotinus coggygria [Common Smokebush] Usually dioecious, so heavy-fruiting clonal material should be used when possible. Can be pruned to low framework each year to promote plant coloration which occurs best on vigorous stems. Misty fruiting panicles give the species its name. The fine-textured hairs on the fruit pedicels and peduncles change colors, being best when tinted smoky pink.
Tree Indiana Native Crataegus crus-galli [Cockspur Hawthorn] The strong horizontal branching is good for softening vertical lines of buildings. The 2-3" thorns can be dangerous, especially around children. Although attractive, some find the small, white flowers malodorous. Fireblight, leaf spot, and cedar-hawthorn rust are among the worst problems to affect this species. Japanese beetles like to feed on hawthorns.
Tree Indiana Native Crataegus phaenopyrum [Washington Hawthorn] One of the finest small trees for winter color. The 1-3" thorns can be dangerous, especially around children. Fireblight, leaf spot, and cedar-hawthorn rust are among the worst problems, although more trouble-free than many hawthorns. Japanese beetles like to feed on hawthorns.
Tree Indiana Native Crataegus viridis [Green Hawthorn] An attractive small tree with beautiful white flower corymbs and bright red persistent fruits. Very adaptable, although leaves are often badly infected by rust so that the entire plant appears to be suffering from the measles.
Tree Crataegus viridis 'Winter King' [Winter King Green Hawthorn] An attractive, nearly thornless vase-shaped small tree with beautiful white flower corymbs and large, bright red persistent fruits. This cultivar was discovered in a fence row by Bob Simpson in Vincennes, Indiana. Very adaptable, although leaves are often badly infected by rust so that the entire plant appears to be suffering from the measles.
Tree Crataegus × 'Vaughn' [Vaughn Hawthorn] This small tree is a hybrid of Crataegus crusgalli x C. phaenopyrum. It is generally grown for its fragrant clusters of white flowers in the spring and prolifically produced red fruits that persist into winter. Due to its numerous thorns, it is best used in areas with low traffic. Highly susceptible to rust.
Shrub Eleutherococcus sieboldianus [Fiveleaf Aralia] Tolerates a wide range of soil and environmental conditions, including dry city conditions and shade. Little seasonal interest other than foliage, but extremely durable shrub. Prickles on stems can make pruning difficult. In poor sites, renewal pruning can improve form. In rich organic soils, renewal pruning can lead to rank growth. Usually dioecious.
Shrub Eleutherococcus sieboldianus 'Variegatus' [Variegated Aralia] This cultivar has attractive, creamy variegated foliage and is more compact than the straight species. Tolerates a wide range of soil and environmental conditions, including dry city conditions and shade. Prickles on stems can make pruning difficult. In poor sites, renewal pruning can improve form. In rich organic soils, renewal pruning can lead to rank growth. Usually dioecious.
Shrub/Tree Euonymus europaeus [Common Spindle Tree] Euonymus europaeus is an adaptable small tree (sometimes large shrub) that can spread and become invasive. The Common Spindle Tree's primary ornamental interest is its attractive and interesting fruits in the fall. Unfortunately, this tree can otherwise be quite unattractive, irregular, and spindley.
