Reed canarygrass (Phalaris arundinacea) has long been recognized as adapted to wetlands and those subject to periodic flooding. In Utah, Wilson (1955) estimate that 40 percent of the valley bottom land is flooded at least part of the year. Much of this land is very dry late in the summer. Forages such as Alsike clover tolerate flooding and some salt but do not perform well under drouth. Work by Bolton (1946) indicated that flooding for 49 day did not cause serious permanent damage to Reed canarygrass. The author baa observed Reed canarygrass growing in a shallow reservoir which is flooded 90 days or more. Reed canarygrass is also one of the most drouth tolerant of the cool season grasses when grown on upland soils.
