Shrub Indiana Native Staphylea trifolia [American Bladdernut] An upright, heavily branched, suckering shrub; sometimes wide-spreading, as a small tree. Used in naturalizing; best reserved for parks and other low maintenance areas; rather nice for foliage effect.
Tree Stewartia pseudocamellia [Japanese Stewartia] In the wild, this specimen can grow up to 60' high, much larger than the mature landscape tree which ranges from 20-40' high. The outstanding, multi-colored bark is rich and flaking, ranging from soft grays and browns to orangish brown. There are no serious pests or diseases for this specimen.
Herbaceous Stokesia laevis 'Purple Parasols' [Purple Parasols Stokes' aster] Native to wetlands of the southeast United States, Stoke's aster is an evergreen perennial with fluffy blue violet flowers. There are no serious issues to watchout for with this plant, although they need to be monitored for caterpillars.
Tree Styphnolobium japonicum [Japanese Pagodatree] A widely adapted tree with good drought and pollution tolerance, and foliage texture comparable to Gleditsia, but a smaller tree and with more seasonal interest. Relatively trouble-free except for fungi that live in weaker twigs that cause twig blight and canker. Fungi invade most readily those twigs killed by cold or self-pruning. Seeds are poisonous. Difficult to train a central leader. More cold sensitive when young.
Tree Styrax japonicus [Japanese Snowbell] Relatively trouble-free. Can be susceptible to Ambrosia beetle and canker. Partial shade best in Zones 7 and 8 due to heat intolerance.
Shrub Indiana Native Symphoricarpos albus [Common Snowberry] Useful as a bank cover or large scale groundcover. Transplants well. This plant has a beautiful fruit show and is shade tolerant, however, it is also a twiggy, "garbage can plant" (collects leaves and blowing debris); this quality (especially prominent in the fall and winter) limits its usability in the landscape.
Shrub Symphoricarpos × chenaultii [Chenault Coralberry] A more refined plant than the parent S. orbiculatus, perhaps more showy in flower and fruit and more useful in the shrub border. Useful as a bank cover or large scale groundcover. Transplants well. This plant has a beautiful fruit show and is shade tolerant, however, it is also a twiggy, "garbage can plant" (collects leaves and blowing debris); this quality (especially prominent in the fall and winter) limits its usability in the landscape.
Shrub Symphoricarpos × chenaultii 'Hancock' [Dwarf Chenault Coralberry] 'Hancock' is a low-growing, wide spreading dwarf cultivar of the Chenault Coralberry that is useful as a groundcover and for erosion control. Transplants well. This plant has a beautiful fruit show and is shade tolerant, however, it is also a "garbage can plant" (collects leaves and blowing debris). 'Hancock' appears to have less of a problem with this than the species type, though.
Shrub Syringa × chinensis [Chinese Lilac] Can become ratty in appearance, and so should be pruned properly on 3 year cycle. Problems with aphids, powdery mildew, scales, and caterpillars, although powdery mildew is worst problem.
Shrub Syringa meyeri [Meyer Lilac] Flowers by the time it reaches one foot tall, very floriferous. Flowers in spring before leaves are fully out. Powdery mildew resistant. Very low maintenance. Flowers can be damaged by a late spring freeze. Best to prune immediately after flowering to promote flower buds for the next year.
