Maintenance

Cut off dead fronds in late winter if desired. Can grow in sun if in standing water; otherwise, it must have moist soil and semi-shade. Propagation: Root division, Spores.

Comments

Fertile fronds appear first as silvery, furry fiddleheads, ultimately becoming stiff, erect, and covered with specialized pinnae, which turn their upper portions into a thick spike of fruit dots – turning from green to chocolate brown. Sterile fronds bend outwards forming a vase-shaped circle enclosing the cinnamon fronds. Superficial roots vulnerable to drying out in summer. Soil stabilization. Provides nesting material for birds.
Previous Scientific Name(s): Osmunda cinnamomea
