Description This is an uncommon plant, found in just a few locations in southern Arizona. Because of its reliance on semi-permanent water many of the localities where this plant historically occured are no longer viable. However, this is an excellent species for low and mid elevation gardens with greywater systems or outdoor showers. In a basin this plant can grow well over 6 feet and produce abundant flowers in the spring, and following monsoons. Blooms are attractive to a huge diversity of pollinators.
