Description of Osmunda regalis (Royal Fern)

Osmunda regalis is royal fern, a big UK native fern for reliably damp ground. It’s one of the best plants for giving a bog garden height without flowers. Once it settles, it looks good from spring right through autumn.

Appearance

It makes a large clump of fresh green fronds that can reach well over 1m, and in the right spot it can push taller. In summer, spore-bearing tips turn rusty brown, which gives a slightly different look at the top of the fronds.

In autumn the foliage often takes on bronze tones before it dies back.

Care Guide

Royal fern likes cool, moist soil and it hates drying out.

  • Sun: Part shade is ideal. It can take sun if the soil stays cool and wet.
  • Soil: Fertile, moisture-holding soil. Neutral to slightly acid suits it well.
  • Water: Damp ground is perfect. It can cope near very shallow water, but it’s mainly a bog plant rather than a true aquatic.
  • Mulch: A yearly mulch of leaf mould keeps it happy and stops the roots overheating.
  • Tidy up: Remove old fronds in late winter before new growth unfurls.

It’s slow to bulk up at first. Don’t move it around. Pick the spot, plant it, then leave it alone.

Suitability for Bog Garden

Osmunda regalis is a top choice for the back of a bog garden or the shady side of a pond. Use it as a backdrop for flowers like Japanese primrose or lobelia, or as a screen to soften a fence.

It also helps with structure. In winter you lose the fronds, but in the growing season it gives a strong, upright shape that stops the bog looking flat.

Space it properly. A mature clump needs room, so don’t cram it tight to smaller marginals.

FAQs

What is the difference between bog plants and marginal pond plants?

Bog plants prefer consistently damp or wet soil but generally do not want to remain submerged in standing water. Marginal pond plants are adapted to grow at the pond edge with their roots or crowns in shallow water. If an area stays flooded for long periods, marginal plants are usually more appropriate.

Do bog plants need to be planted in water?

No. Bog plants need reliably moist or wet soil rather than permanent standing water. They are suitable for bog gardens, damp borders and moist areas around ponds, but most should not be planted underwater.

How do I make a bog garden for bog plants?

Choose an area where the soil can be kept consistently moist and improve it with plenty of organic matter. A purpose-built bog garden can also be created by using a liner that retains moisture while still allowing some drainage, then filling the area with suitable soil before planting.

Can bog plants grow in shade?

Some can. Many bog plants grow best in sun, but there are species that tolerate partial shade. The important factor is maintaining the moist soil conditions the particular plant requires, so check the individual plant's light requirements before choosing its position.

What are the best bog plants for wildlife?

Flowering bog plants can provide nectar and pollen for insects, while dense foliage creates shelter around a pond or damp garden. A mixture of flowering periods, heights and foliage types generally provides more varied habitat than relying on a single species.

What are the best pond plants for a wildlife pond?

The best wildlife pond plants provide a mixture of underwater cover, surface shade, flowering habitat and places for aquatic insects to emerge. A balanced pond can include oxygenating plants, marginal plants and floating-leaved plants such as water lilies. Native species are particularly useful for supporting UK pond wildlife.
