Which image in the poem reflects the end of spring?

There are many images of late spring in poetry, and the most common ones are as follows. Give an example of each picture:

Fall in love (cherish spring for fear of early flowering, not to mention countless falls in love)

Flying catkins (cobwebs painted on eaves, flying catkins in Yogyakarta)

Willow (don't lean on the hedge, the sun sets, and the willow is heartbroken)

Tobacco, catkin (Yichuan tobacco, Mancheng catkin, plum yellow rain)

Huayang (in detail, it doesn't seem to be Huayang, but one thing is tears. )

I hope my answer can help you.
