A genus of large, perennial grasses or reeds, particularly the giant reed, known for fast growth and bamboo-like appearance.
Direct from Latin arundo, the Roman name for reed plants, possibly from an Indo-European root meaning 'to stand' or 'to be stiff.'
Giant reed (Arundo donax) grows so aggressively it's now an invasive species on five continents—ancient Romans loved it, but modern farmers call it ecological kryptonite.
