Osmunda regalis var. spectabilis, the American royal fern, is a majestic spectacular” fern that thrives in bogs and wet areas where it frequently reaches four feet or more. Here it will happily tolerate almost full sun as well. Look for it as a dominant plant in botanical garden waterside plantings. As a truly ancient deciduous species it carries its green spores on separate stalks which will persist as tan frond tops. It is not limited to life in swamps.
