Poison Ivy

Toxicodendron Radicans

Design with this plant

Overview

Poison Ivy (Toxicodendron radicans) is a pernicious, native North American plant, identifiable by its trio of leaflets. Thriving in zones 4-10, it can spread as a groundcover or climb up to 30 feet as a vine. The plant contains urushiol, causing severe skin irritation upon contact. Due to its invasive nature and health risks, it's generally unwelcome in landscapes. Exercise caution: even dead plants can still cause reactions.
