Invasive Plant Bush Honeysuckle (IMAGE) Washington University in St. Louis Caption This is a wall of bush honeysuckle in a park in St. Louis. Half the time that unidentifiable shrubby green thing is the invasive plant Amur honeysuckle, Lonicera maackii. A new study shows that whitetailed deer shelter in bush honeysuckle, dropping larval ticks there that carry diseases called the ehrlichioses. In this way an invasive plant is indirectly linked to emerging zoonoses.
