Poison Ivy

Poison ivy (Toxicodendron radicans -- eastern poison ivy) typically grows as a vine or shrub, and it can be found throughout much of North America (except in the desert, Alaska, and Hawaii). It grows in open fields, wooded areas, on the roadside, and along riverbanks. It can also be found in urban areas, such as parks or backyards. Poison ivy plants typically have leaf arrangements that are clustered in groups of three leaflets, though this can vary. The color and shape of the leaves may also vary depending upon the exact species, the local environment, and the time of year. The plant may have yellow or green flowers, and white to green-yellow berries, depending on the season.
