What do yellow catkins look like?

Yellow catkins are long, slender, dangling structures that hang from trees and shrubs. They are usually yellow in color, although they can also be green or even brown depending on the species.

Here's a more detailed description:

Shape and Size:

* Elongated and cylindrical: They resemble tiny, furry sausages.

* Size varies: They can be anywhere from a few centimeters to several inches long.

* Flexible and pendulous: They hang down gracefully from the branch.

Appearance:

* Covered in small scales: These scales are often overlapping and give the catkin a textured, scaly appearance.

* Flowers are tiny and inconspicuous: Each scale hides a small, individual flower within its base.

* Pollen-producing: The male catkins release pollen, which is often visible as a yellow dust.

Examples of trees with yellow catkins:

* Willow trees

* Hazelnut trees

* Poplar trees

* Alder trees

Note: Yellow catkins are often associated with spring, as they typically appear during this time of year. However, some species may have catkins in other seasons.
