When will the willow blossom?

Willow blossoms in April and May every year. It's catkin.

Generally speaking, the most vigorous season for willow growth is spring, with the flowering period from March to April and the fruit maturity from April to May. There are differences between varieties. Willow is a perennial tree with a long growing period. In order to maintain the growth of branches, it needs to disperse the leaves through germination and then make the branches longer.

Willow is a plant that is particularly sensitive to temperature changes. Once the temperature drops below 10℃ in autumn, the energy is gradually transferred to the heel and cadres, and overwintering buds grow next to the original leaves. Next spring, as long as the average temperature rises above 10℃, willows will compete to sprout.

Catkin leaves are narrowly lanceolate, 9-65438 0.6 cm long and 0.5-65438 0.5 cm wide, with long and sharp tips, wedge-shaped bases and serrated edges; Petiole length (3-)5- 10mm, pubescent; Stipules only grow on budding branches.

Catkin seeds are small, oblanceolate, 1-2mm long, yellowish brown or grayish black. There are longitudinal grooves on the surface, and white filamentous villi are clustered at the top, which is 2-4 mm long and clustered around the seeds.

If it is troublesome for catkins to fly into clothes in spring, you can do a good job of protection, wear masks and scarves, and try to avoid catkins.
