There are several different subspecies of A. glomeratus with different affinities for upland and wetland conditions. A. glomeratus var. glaucopsis is notable as it has a blue-purple coloration and is almost always found in wetlands.  It is sometimes considered to be a separate species A. glomeratus var. pumilus has the widest distribution in Florida and based on the relative numbers of herbarium specimens, likely the most common. A. glomeratus var. hirsuitior is widespread but probably less common than var. pumilis. A. glomeratus var. glomeratus has no documented herbarium specimens in the southern half of the peninsula. Uses of the latter 3 varieties should be similar as their habitats are similar. Background plant in casual landscape. Fruit stalks start out silvery green and transition to and orangy brown. Retains the old stalks through the winter.
