WhippingWood

Whippingwood trees, or "Murderbushes" as they are known Colloquially, are small bushes that are known to extend branches and tighten them around anything that approaches too closely or too quickly. Whatever they grab hold of they tighten and never let go, proceeding to whip it violently when detecting movement. It's presumed that originally these plants developed this strategy in order to take hold of and break the necks of small animals, but in modern times they sometimes grab hold of misplaced weapons, leading to the rumors of "Sword Forging plants raiding villages."
