Viburnum lantanoides (commonly known as hobble-bush, witch-hobble, alder-leaved viburnum, American wayfaring tree, and moosewood) is a perennial shrub of the family Adoxaceae (formerly in the Caprifoliaceae), growing 2–4 meters (6–12 ft) high with pendulous branches that take root where they touch the ground. These rooted branches form obstacles which easily trip (or hobble) walkers – hence the common name.
