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.

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).
