Description
Willows are trees and shrubs of wet or moist habitats. They have simple alternate deciduous leaves that are usually lance-shaped, entire or toothed along the margins. The petioles are much shorter than the blades, sometimes with glands at the summit. Male and female flowers are produced separately in densely flowered catkins that appear before or immediately after the leaves unfold. The fruits are small, cone to lance-shaped capsules, 2-valved, sessile or stipitate. Willows are extremely difficult to distinguish from one another. Much variation occurs within a species and relatively small differences separate species. They also tend to hybridize resulting in intermediate characteristics.
Interesting facts
Willows occur in floodplains, along streambanks, lake and pond borders, wet meadows, ditches, swamps, fens, and other moist places. They may form dense stands by putting out root shoots.
Thick monocultures can become established in almost any area with available moisture. Root systems often interfere and cause problems with water supply and drainage systems, i.e., water mains, sewer systems, culverts, etc.
