Additional information about Calliandra anomala may be found here. A vigorous perennial herb growing up to 6 feet tall, composed of many long, slender, grasslike leaves up to 0.75 inch wide rising from a horizontal rootstock. The flowers are minute and greenish-yellow in color, occurring on a 4 inch long spike resembling a finger. The fruit is berrylike. Native to eastern North America, Europe and Asia.
Calamus is hardy throughout the U.S. and much of Canada.
It thrives best in a rich soil, but can be grown in shallow water on dry land. It is propagated by division of the rootstock in spring or fall. Pieces of the rhizome should be planted horizontally, an inch or two deep, a foot apart in each direction, with the leaf-shoots upward. They can be planted in marshes and at the edges of ponds and streams. They will do well in the garden if the soil is rich and is kept moist by frequent waterings.
