This handsome vertical growing perennial resembles a giant horsetail, and indeed is found naturally alongside streams and in moist seeps. Reaching almost 7’ tall (larger in ideal settings) and forming a dense clump of cylindrical stems ringed with thread-like branches in tight whorls, this large species is well suited to poolside gardens, specimen plantings and oversized containers. Cinnamon-colored papery leaf bracts also line the stems creating additional ornamental interest.
