Royal ferns have very long fronds with lance-shaped leaves resembling the leaves of the ash or locust trees. It spreads slowly, like other Osmundas, but individual plants remain. After many years large stands will be in place around a large central plant.

How to Grow: Royal ferns prefer open shade and highly acid, very wet soil. Plants in the Florida wetlands are tree-like and quite impressive. Divide in spring, planting the crowns just at the soil level.
