Willows are dioecious plants with male stamen flowers on one plant and female carpel flowers on the other. They are indiscriminate in terms of soil, fast-growing. Willows are used in various sectors of the economy. Various organic compounds are obtained from the bark, such as salicin, tannings, black dyes, etc. In the past, salicylic acid, which is part of various painkillers such as aspirin, has also been obtained. Willows often grow as a pioneer species, the first to spread into abandoned areas. Willow branches sprout very well, so they are often used to strengthen the terrain. Ornamental willow species and varieties are cultivated in garden and park plantings
