Shrub Rhododendron × 'P.J.M.' (P.J.M. Hybrid Group) [P.J.M. Rhododendron] One of the most cold tolerant flower buds of the evergreen rhododendrons. Flowers can become a dirty looking lavender soon after opening. Quite variable in form and flower color. Avoid harsh, dry, windswept sites. Susceptible to a large number of pests and diseases, which can largely be prevented by good cultural practices.
Shrub Rhododendron × 'Purple Gem' [Purple Gem Rhododendron] 'Purple Gem' is a compact, rounded, dwarf rhododendron that is hardy to 15 degrees Fahrenheit. Avoid harsh, dry, windswept sites. Susceptible to a large number of pests and diseases, which can largely be prevented by good cultural practices.
Shrub Rhododendron sp. [Rhododendron] The massive genus of Rhododendron has between 800 and 900 species and countless hybrids and cultivars of numerous sizes, flower colors, and hardiness levels. Plants of this genus can be evergreen or deciduous. Azaleas are part of the Rhododendron genus.
Shrub Rhododendron × 'Victor' (P.J.M. Hybrid Group) [Victor Rhododendron] The compact and slow-growing cultivar 'Victor' is the earliest of the 'P.J.M' Hybrid group to bloom. One of the most cold tolerant flower buds of the evergreen rhododendrons. Flowers can become a dirty looking lavender soon after opening. Susceptible to a large number of pests and diseases, which can largely be prevented by good cultural practices.
Shrub Rhodotypos scandens [Black Jetbead] Relatively trouble-free. Tolerant of a variety of soils and environments, particularly dryness and shade. Commonly becomes straggly if growing in a site that is too dry or too wet.
Shrub Indiana Native Rhus aromatica [Fragrant Sumac] A highly variable species in both ultimate height and fall foliage color. Color probably also varies with soil type, possibly as a function of moisture content. Plants are native to dry, sandy, and rocky soils, and usually color well under these conditions. Useful for bank stabilization since it develops roots on stems touching the soil. It also suckers. Can spread too quickly for some sites (spreading rhizomes). Shear to ground to rejuvenate (try a brush-hog).
Shrub Rhus aromatica 'Gro-low' [Low Growing Fragrant Sumac] 'Gro-low', as the name implies, is a very low-growing (and popular) female cultivar. Rhus aromatica is native to dry, sandy, and rocky soils, and usually colors well under these conditions. Useful for bank stabilization since it develops roots on stems touching the soil. It also suckers. Can spread too quickly for some sites (spreading rhizomes). Shear to ground to rejuvenate (try a brush-hog).
Shrub Indiana Native Rhus copallinum [Flameleaf Sumac] The Flameleaf Sumac is a large shrub or small tree known for its extraordinary, "flaming" red fall color. Its form is initially compact, but then becomes quite open and irregular with age. Spreads by root suckers and forms large colonies, making it inappropriate for small areas.
Shrub Indiana Native Rhus glabra [Smooth Sumac] Large, club-like fruit clusters and rather coarse compound leaves make this a plant that can best be appreciated from a distance, and so it is at its best in large-scale plantings. Picturesque branches. Hard to kill this plant. Can be rejuvenated by cutting to ground in late winter. Plants are dioecious, so only females have the fruiting interest, but all plants are reliably colorful in fall foliage. Spreads rapidly by suckers.
Shrub Rhus typhina 'Bailtiger' [sold as Tiger Eyes®] [Cutleaf Tiger Eyes Staghorn Sumac] The Tiger Eyes cultivar makes a great landscape plant as it suckers less than the species, and for it's nice foliage.
