Description

Cat's Ear is a perennial weed from Eurasia in the aster family. It has naturalized on every continent except Antarctica. It has a long taproot and a basal rosette of leaves. The flowers are often mistaken for dandelions as they both form wind-borne seeds. It is found in lawns, fields, roadsides and any disturbed area. 

Cat's Ear tolerates a wide range of conditions and readily grows in most soil types but is not usually found in wetlands. It produces many seeds per plant per year and each seed can become a mature plant in 2 months. It is considered invasive in some areas.
