What is poplar fluff?

Poplar fluff refers to the lightweight, cotton-like fibers produced by the seeds of poplar trees, particularly the Eastern Cottonwood. These fluffy fibers are dispersed by the wind during the tree's reproductive season, typically in late spring to early summer. While they can create a picturesque scene, they can also cause nuisance issues, such as clogging gutters or causing Allergies in sensitive individuals.
