Osmunda cinnamomea

Osmunda is comprised of a dozen or so species of deciduous, terrestrial ferns. They are native to damp places nearly worldwide. Sterile fronds are pinnate or pinnatifid and turn yellow or golden brown in the fall. Fertile fronds produce clusters of greenish sporangia, which darken to brown or black. Grow these ferns in a damp area of the garden, such as in a border or at waterside.

Noteworthy Characteristics

CareMost species prefer lightly dappled shade but some can take full sun. All like moist, fertile, humus-rich soil that is preferably acidic.

PropagationBecause spores lose viability quickly, sow them at 59-61°F within 3 days of ripening in summer. Or divide clumps from established colonies in early spring or in autumn.

ProblemsProne to rust.
