Where can you find poison ivy, oak and sumac plants?

Poison Ivy:

Grows throughout much of North America, including all Canadian provinces except Newfoundland (and the Territories) and all US states except Alaska, Oregon, Hawaii and California. The plants can grow as a shrub up to about 4 feet tall, as a groundcover, or as a climbing vine. The color of the three almond-shaped leaflets range from light to dark green and turn bright red in the fall. The plant's berries are a grayish-white color.

Poison Oak:

Poison oak is found along the Pacific Coast of North America including Washington, Oregon and California, and along the Atlantic Coast. Poison oak can grow as a dense shrub in open sunlight or a climbing vine in shaded areas. The three leaflets have scalloped edges resembling the leaves of a true oak and can be bronze, bright green, yellow-green or reddish depending on the season. The plant can produce greenish-white or tan berries.

Poison Sumac:

Poison sumac grows exclusively in very wet or flooded soils, usually in swamps and peat bogs, in the eastern United States as far west as Idaho and Canada. Poison sumac has compound leaves with 7-13 leaflets, and the veins from which the leaflets grow are always red. The plant grows as a shrub and produces fruit that is a small white or grey berry.
