Royal Fern has a huge native range in wetlands and swamps from tropical South America up into southern Canada and in Eurasia and Africa. It is sold by some larger, diverse conventional nurseries and native plant nurseries, but it is not common in landscapes and gardens. Most of the gardening public does not know this species and it does need constantly moist or draining wet soil to do well. This species produces brown fertile leaflets at the tips of the fronds. I would say this is the tallest and biggest fern species that I know of.
