Description
Description

Horseweed (Conyza canadensis) is an upright, fast-growing plant with narrow, bristly leaves arranged in dense, alternate patterns along its stem. It produces tall, spindly stalks topped with clusters of small, white to pale pink flower heads that resemble tiny daisies. Also known as Canadian Fleabane or Mare’s Tail, this plant is native to North America but has spread widely across Europe, Asia, and other regions as a highly adaptable and invasive weed.

Common in agricultural fields, roadsides, and disturbed soils, Horseweed is a colonizing shrubby weed that thrives in poor conditions and is known for its rapid seed production and wind dispersal. It has developed resistance to certain herbicides, making it a persistent challenge in farming and land management. Despite its weedy nature, it has historical use in traditional medicine and folk remedies. Its resilience and opportunistic growth make it a defining species of transitional, disturbed environments.

Invasive weeds are non-native plant species that aggressively spread in new environments, often outcompeting local vegetation and disrupting ecosystems. These plants typically establish themselves in disturbed habitats such as roadsides, fields, wetlands, and forest edges.
