Royal Fern - Osmunda Regalis

The Royal Fern is a large, striking fern with feathery fronds and a distinctive crown of fertile fronds. It is typically found in wetland habitats and is appreciated for its ornamental appeal in gardens.

The fern is distinctive from other plants in the class because of its notable size. Specifically, this is one of the largest that grows outside of tropical zones in the United States. Also known as the osmunda regalis, the plant thrives in areas of the yard that are moist, including both shady and partially shady spots. Why should you include it in your landscaping plans?

The Appearance Of Royal Fern

The plant is appropriately named because it can grow up to six feet tall, and its size at maturity often makes it a solid focal point in yards. The fronds can be as comprehensive as 16 inches and feature up to nine pinna pairs, each with up to 13 pinnules. These qualities, combined with the healthy green color and the point shape of the fronts, add a rich texture to your yard that elevates aesthetics.

The Wildlife Attraction and Tolerance Of Royal Fern

While some wildlife is welcome in your yard, others can cause considerable damage and should be deterred. The potential damage from foragers like deer and rabbits is deterred as these animals do not use this plant for food. However, turtles, birds, and frogs, which generally do not cause damage, often seek shelter in their bushy leaves.

While hungry insects often feed on various types of plants, it is well-known for repelling them. Specifically, the recognizable leaves have particular proteins that repel many kinds of insects. Any insects that do find their way to these plants often become food for the birds and other animals that live under the fronds for protection from the elements and their natural predators. 

When Royal Ferns are planted three feet apart, as recommended, there is little concern about them outgrowing their allocated space. The plants grow only a few inches yearly and do not need to be cut back to prevent overgrowth. As a result, it takes many years for the plant to reach its full size, and minimal care of this low-maintenance plant is required.

Care

Royal Ferns thrive in moist, well-drained soil with plenty of organic matter. They should be consistently watered, especially during dry spells. The base should be mulched to retain moisture and prevent weeds. Dead fronds should be pruned to maintain their appearance and health.

Plant Reproduction

Royal Fern spreads via underground rhizomes, producing new shoots

Choose early spring or fall when the soil is moist and cool to plant healthy bare-root ferns. You can also use dormant plants to grow year-round. When you arrive, please soak the roots in water for several hours to rehydrate them. Ferns thrive in moist and shaded areas. Dig a hole wide and deep enough to spread out the roots comfortably. Position the fern so the crown (where the roots meet the fronds) is just at or slightly below ground level. Gently backfill with soil firmly around the roots, and thoroughly water to settle the soil and eliminate air pockets. Apply a 2-3 inch layer of mulch for weed control and to retain moisture, ensuring the mulch does not touch the crown. Water during dry periods is used to keep soil moist but not soggy. Avoid fertilizing in the first year, as ferns prefer nutrient-rich soil over direct fertilization.
