Willows are shade tolerant and typically short-lived. They require disturbances to outcompete conifers or large deciduous species. The seeds are tiny, plentiful, carried by wind and water, and viable only for a few days; they require warm and moist conditions to take root. The plants can also reproduce vegetatively from decapitated stumps and ...
The black willow is the only United States native willow species to be used as timber for a variety of different items. Black willow lumber is used in furniture and shipping containers. The largest production site for black willow timber was in Louisiana at its peak during the 1970s. [20] The wood of Salix nigra is very lightweight.
Salix reticulata, the net-leaved willow, [1] or snow willow, [2] is a dwarf willow, native to the colder parts of Europe, North America, and Northern Asia. It is found in the western United States ( Salix reticulata subsp. nivalis ), including the Sierra Nevada and Rocky Mountains.
This tree is mostly deciduous during the winter, but can start growing back leaves early during warm snaps in the winter. Yellow flowers grow in drooping catkins. In female red willows, the catkins turn into tufts of cottony seeds, which are windborn, often in large quantities, for 2-3 weeks in the spring. [4] Flowering Time: Dec--Jun [5]

The leaf edges are generally entire, though sometimes finely serrated. The leaves are dull blue-green in color and smooth in texture when mature; new leaves are coated in downy hairs. The leaves are up to 5 in long and 1.5 in wide. Like other willows, this plant is dioecious, with male and female plants producing small, dangling catkins.
It has round, shiny green leaves1–4 cm (1 ⁄ 2 – 1 + 1 ⁄ 2 in) long and 6 cm (2 + 1 ⁄ 4 in) broad; they are pubescent, with long, silky, silvery hairs. Like the rest of the willows, Arctic willow is dioecious, with male and female catkins on separate plants. As a result, the plant's appearance varies; the female catkins are red ...
