Mystery Graph: Japanese knotweed (Fallopia japonica)

Use this activity to kick off a Vital Signs investigation focused on invasive Japanese knotweed (Fallopia japonica). Use your graphing skills to figure out and explain what happened during a 3-week study of Japanese knotweed growth. Japanese knotweed’s early, aggressive spring growth helps it out-compete native species for sunlight, space, and nutrients.
