It bears handsome, glossy, dark-green leaves from spring to fall, and its catkins provide mild interest in winter and early spring.
Requiring sun but thriving in most soils, it excels as a shade or screening tree in sites that are too damp or barren for other trees. It may be invasive in some...

Some are arrow-shaped and all have the petiole (leaf stem) attached inside the leaf edge. Large, prominent, variously colored veins often decorate the leaves. The leaves top long, variously-hued petioles which grow directly...
