The Story
Plant Bio
An evergreen fern featuring two distinct types of fronds: sterile, leathery, dark green fronds that are low-spreading, and taller, erect, fertile fronds that appear in the center and die back in winter.
Distinctive for its dimorphic fronds. The sterile, evergreen fronds form a neat, spreading rosette, while the central, fertile fronds stand upright like dark combs, creating a unique two-tiered appearance.
