Poison ivy can be found in the Edwards Plateau region growing in woodland edges and near stream banks. All parts of this woody-stemmed vine contain a poisonous oil called toxicodendrol which causes itching and blisters in many people. However, not all people are allergic to this vine. The leaves with the “leaflets of three” vary in size and shape and are a shiny green color. The stems can be found growing up trees in woody areas and can be six inches in diameter. The small flowers are greenish white and form clusters. The white, waxy fruits are between 1/8-1/4 inch in diameter and are eaten by bobwhite quail, turkey, and many other gallinaceous birds. It has been noted that white-tail deer eat the leaves.
