Smooth Cat's Ear, commonly known as Smooth Cat's Ear, is a native plant of the Mediterranean region but has now dispersed throughout the globe. It is classified as a weed due to its prolific reproduction capabilities and rapid spread, often outcompeting native flora for resources such as sunlight, water, and nutrients. The weed's vigor and tenacity even in harsh conditions further exacerbate its invasiveness, making it a significant nuisance in gardens where it crowds out desired plants. Smooth Cat's Ear's harmfulness is primarily due to its ability to dominate gardens, pastures, and agricultural land, negatively impacting biodiversity and causing potential yield losses in crops. The primary method of spread for smooth Cat's Ear is through wind-dispersed seeds. The weed produces a large number of seeds that can remain dormant and viable in the soil for many years, contributing to the plant's persistence and invasive character.
