Reproduction
Black willow is dioecious (having separate male and female plant)s. No consistently reliable morphological characteristics are associated with the identification of the sexes, which are indistinguishable except during flowering and seed development.

The Black willow also uses vegetative reproduction, a form of asexual reproduction in plants, in which multicellular structures become detached from the parent plant and develop into new individuals that are genetically identical to the parent plant. For example, liverworts and mosses form small clumps of tissue (called gemmae) that are dispersed by splashing raindrops to form new plants. Bulbs, corms, offsets, rhizomes, runners, suckers, and tubers are all important means of vegetative reproduction and propagation in cultivated plants.  

Ecology


The Black willow’s native habitat is eastern North America, Nova Scotia, South Ontario, west Nebraska, South east of Arizona and Florida, and north-east of Mexico. Usually the species of willows are found in wet place such as streams, swamps, and lakes, sometimes in pure stands.
