Flowering rush Butomacea Family Butomus umbellatus Key identifying traits Freshwater aquatic plant resembling a large sedge Leaves are sword shaped, narrow and triangular in cross section Flowering stems are fleshy and spirally twisted Showy, pink flowers grow in umbels at ends of stems (but not all plants flower) June-August Grows as a shoreline emergent plant with upright, stiff foliage or as a wholly to partially submersed plant with flexible leaves Fleshy, rhizomatous roots with “bulbils” Biology and ecology Perennial plant reproducing by rhizomes, bulbils and, possibly, seeds Grows along muddy shores of lakes, streams, ditches, but can grow out into water as deep as 20’ and be totally submersed It is the single member of it’s family-it is not a true “rush” It is native to Eurasia Jenifer Parsons, DOE, holding plant. Top & root photos hers. Control Prevention – Learn to identify plants; looks like a large grass or sedge-must learn to distinguish Biological – No known biological control in our area Cultural – Does not seem to invade healthy shoreline communities as quickly as disturbed sites, but it can still invade Mechanical – Digging and covering control trials are currently underway-it may be difficult to remove all root parts. Raking and cutting are not effective Chemical –Plants that are mostly above water are more susceptible to foliar treatment with aquatic herbicides, but control has been inconsistent. Trials are underway in Montana, Idaho and WA. Flower Photo Leslie J. Mehrhoff, Univ. of Connecticut, Bugwood.org Where found – Found along shore and well out into the waters of Lake Spokane in 2010. Also found in Whatcom, Benton, Yakima and Pend Oreille counties. Large infestation in Flathead Lake, MT and smaller populations elsewhere in the state and in Idaho.
