Osmunda regalis ‘Royal Fern’

The large, deciduous ‘Royal Fern’ has leafy looking fronds that are broad but airy and graceful. In summer, a cluster of fertile, rust-colored, delicate fronds is produced from the center of the fern. From a distance, this looks like a flower spike and explains its old name of ‘flowering fern’. Royal ferns create a focal point to any bog garden, pond margin or flower border. Grow them in sun or partial shade in moist, humus-rich soil.

This fern is an excellent selection for wet areas along ponds, streams, water gardens or in bogs. Also grows well in shaded borders, woodland gardens, wild gardens or native plant gardens. This is a fern that can suggest a tropical look but without all the fuss of winter protection. The Royal Fern has a long life span relative to most other plant species.

Ferns are perfect for the background of the garden or in a woodland setting. Their gracefulness make them especially suited for companions to the Hosta. Performs well in sun but prefers partial shade.

General Information +

Botanical: Osmunda regalis

Common: Royal fern

Family: Osmundaceae

General Characteristics: Provide a partially shaded or shaded growing area that has a moist soil. The plant can be grown near water or in swampy conditions. Leave dead fronds on the plant through the winter as they help protect the crown. Royal Fern is a tall, deciduous fern which typically grows in clumps to 24-48" tall, but with consistent moisture in optimum growing conditions can reach 6' in height. Broad fronds have large, well-separated pinnae (leaflets) which give this fern an almost pea-family appearance. Fronds typically turn yellow to brown in autumn. Spores are located in brown, tassel-like, fertile clusters at the tips of the fronds, thus giving rise to the additional common name of flowering fern for this plant. Osmunda fiber used in the potting of orchids are from the fibrous roots of these ferns.

Planting/Care Instructions +

Pests or Diseases: No serious insect or disease problems.

Planting Instructions: May be planted in any well-drained soil. Dig a hole large enough to encompass the roots without bending or circling. Set the plant in place so the crown (part of the plant where the root meets the stem) is level with the soil surface. Water thoroughly. Easily grown in medium wet to wet soils in part shade. Prefers moist, rich, humusy, acidic soils, but adapts to lesser conditions.
