This document discusses poison ivy identification and growth patterns. It describes two different poison ivy root systems - the "Heart Root Archer" which sends out runners to spread rapidly, and "Back Beat" which grows thickly without spreading. Pictures show a 26-foot tall poison ivy plant growing on a steel tower, with vines up to 3.5 inches wide, demonstrating its ability to thrive in difficult conditions. The document advocates learning to identify poison ivy to avoid accidental exposure.
