Has daisy type yellow flowers in the summer. The leaves are rough and form a cup shape around the square stem hence the common name Cup Plant. This plant will make a very large clump so give it some room, will reach heights of 8 feet or more and will have a spread of 3 to 5 feet. Very hardy and prefers moist soils but will also grow in drier locations, will not get quite as tall if the soil is dry. A large clump of this puts on quite a show during the summer months.
