royal fern Interesting Notes

The American Royal Fern (Osmunda regalis var. spectabilis) is a spectacular, majestic fern that thrives in bogs and wet areas where it frequently reaches four feet or more. It is not limited to life in swamps, however, and when kept moist grows well in the shady garden although it will be more modest in size. 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.  This native is easy to establish in gardens from Zones 2–10. - Casa Flora
