This is a common species found throughout most of North America and Eurasia that grows in wet soils along watercourses and bodies of water, in swamps, bogs, marshes, and in moist open woods. It grows about 3 to 6 feet high with unbranched, rough, upright stems with sheaths of tooth-like leaves and a larger cone-like strobilus on the tip that produces the spores. I was allowed to take a clump from a customer's yard in southeast Pennsylvania some years ago, and I put it in a pot and had it for a few years. I did not want to plant it in the ground because it spreads like crazy from underground rhizomes. However, I remember a clump growing at Chanticleer Gardens that was surrounded by flat stone blocks that was kept in check and looked good. It can be grown in water up to 4 inches deep.
