Osmunda comprises medium to large deciduous ferns typically found in moist environments. They feature upright or arching fronds that are either pinnate or bipinnate. Spores are produced on modified pinnae or on distinct, smaller fronds.

Osmunda japonica is a deciduous fern characterized by its upright, ascending, or occasionally creeping rhizome. It generates a group of green fronds that can reach heights of up to 150 cm and widths of 50 cm. The fertile fronds, which bear spores, grow more vertically and display a bronze color.

Osmunda regalis 'Bulbifera'

Osmunda regalis 'Purpurascens' features vibrant red to purple young fronds that slowly transition to green as the season progresses. The stems maintain their reddish-purple hue throughout the growing period. This cultivar produces upright bipinnate fronds, characterized by narrower, more finely divided leaflets and more widely spaced pinnules compared to the typical O. regalis.
