Osmunda Regalis, commonly known as ‘Royal Fern’ and holder of the prestigious RHS Award of Garden Merit, is a magnificent native fern species that is highly valued for its beauty and versatility. This fern is one of the largest and most striking species, with tall fronds that can grow up to 2 metres in height, making it a popular choice for landscaping, gardens, and natural areas.

The ‘Royal Fern’ has a unique appearance, featuring a tall, vase-like structure with lush, green fronds that are finely divided and feather-like. The fronds emerge in the Spring and mature over the Summer, turning a rich, golden brown in the Autumn. In addition to its visual appeal, Osmunda Regalis is also known for its hardiness, adaptability, and ease of cultivation.

The Osmunda Regalis are easy to grow and care for, making them an excellent choice for both novice and experienced gardeners. They prefer moist to wet soil and partial to full sun exposure. The fern can tolerate some shade, but too much shade can reduce its growth and vibrancy.

One of the unique features of this Osmunda is its ability to thrive in a range of growing conditions, from wetlands and bogs to drier soils. It is also known for its ability to absorb and remove pollutants from the soil, making it a valuable addition to wetland restoration and conservation projects.

How to care for your Osmunda Regalis

  • Light: Prefers partial to full shade. Avoid direct sunlight, as it can scorch the leaves.
  • Watering: Keep the soil moist, but not waterlogged. Water regularly, especially during hot and dry weather.
  • Soil: Prefers well-drained, acidic soil. If you are growing it in a pot, make sure the pot has drainage holes and use a high-quality potting mix.
  • Fertiliser: Does not require fertiliser, but you can use a balanced, slow-release fertiliser in the Spring to promote healthy growth.
  • Pruning: Remove any dead or yellowing fronds from the plant. Pruning can be done in the Autumn or early Spring before new growth appears.
  • Winter Care: In cold climates, it may die back in the Winter. Cut back the dead fronds in the Spring and new growth should appear.

By following these simple tips, you can enjoy the beauty of Osmunda Regalis in your garden or indoor space for years to come.
