About plant names...

Black willow is a common North American native, and is named for its dark gray-brown bark.

Identification: This willow is 33-98' (10-30 m) tall, rarely up to 148' (45 m). Its trunk(s) reach 20-31" (50-80 cm) in diameter. Leaves are 3-6" (7.6-15 cm) long and about ½" (1.3 cm) wide, with fine serrations and sharp tips, growing alternately to each side. A small rounded leaflike stipule encircles the stem at the base of each leaf, an identifying feature. It forms slender twigs, orange-brown in color. Sometimes these twigs are present in great profusion. It is found in or near wet soils, where it often stabilizes stream banks.
