Safety Overview
1.Parthenium Integrifolium — Overview
Parthenium integrifolium, commonly known as Wild Quinine or American Feverfew, is a robust herbaceous perennial belonging to the extensive Asteraceae family. This distinctive plant is indigenous to the eastern and central regions of North America, flourishing in diverse habitats such as prairies, open woodlands, and savannas. It typically exhibits an upright growth habit, reaching a mature height of 2 to 4 feet (0.6 to 1.2 meters), occasionally taller in optimal conditions.
The basal leaves form a prominent rosette, characterized by their ovate to lanceolate shape and often soft, hairy (tomentose) texture, sometimes extending up to 12 inches (30 cm) in length. As the growing season progresses, sturdy, leafy stems emerge, culminating in a showy inflorescence. The plant produces numerous small, daisy-like flower heads, each composed of pristine white ray florets encircling a dense central disc of yellowish-green tubular florets.
These flower heads are arranged in a flat-topped, corymbose panicle, creating a striking display from late spring through the summer months. Parthenium integrifolium develops a deep, taproot-like root system, which significantly contributes to its remarkable drought tolerance once established. Its resilience and adaptability to various well-drained soil types and preferences for full sun to partial shade make it a valuable species for ecological restoration projects, pollinator gardens, and naturalistic landscapes, offering both aesthetic appeal and vital ecological support.
