Golden-scaled male fern

Sun

Partial shade to full shade; tolerates some morning sun if the soil stays moist.

Water

Keep evenly moist during establishment. Established clumps tolerate brief dry spells, but prolonged dryness causes browning and poor growth.

Soil

Humus-rich, moist but well-drained soil; tolerates clay and a broad range of soil pH if drainage is adequate.

Height

2-4 ft (0.6-1.2 m)

Spread

2-3 ft (0.6-0.9 m)

Foliage

Evergreen. Deep green, lance-shaped fronds form an upright, arching shuttlecock. Golden-brown scales cover the stems and unfurling fronds; mature foliage is firm and leathery.

Growth rate

Moderate

• Water regularly through the first growing season, wetting the root zone thoroughly.
• Mulch annually with leaf mould or compost, keeping the crown uncovered.
• Water established plants during prolonged dry weather, especially beneath trees.
• Avoid heavy feeding; an annual compost mulch is usually sufficient.
• Plant with the crown at soil level rather than burying it.

Pruning. In late winter or early spring, cut dead and battered fronds close to the base before new growth unfurls. Leave healthy evergreen fronds in place and avoid cutting emerging croziers.

Late winter

Remove collapsed or weather-damaged fronds without damaging the crown.

Early spring

Apply leaf mould or compost around the clump, leaving the crown clear.

Spring

Plant new ferns or divide established, multi-crowned clumps; water thoroughly.

Summer

Check soil moisture during dry spells and water deeply when needed.

Autumn

Plant in mild areas while the soil is moist, allowing time for roots to establish before freezing weather.

Winter

Leave sound fronds standing for shelter and structure; avoid disturbing frozen crowns.

• Plant in groups beneath deciduous trees to give a woodland border a strong, repeated foliage shape.
• Combine with hostas and brunneras for contrasting leaf sizes and textures.
• Use behind low groundcovers along a shaded path, allowing room for the arching fronds.
• Grow in a large, well-drained container in a shaded courtyard, where the golden new growth can be seen closely.

Garden styles it suits: Woodland, English country, Japanese, Green on green, Secret garden and Low-maintenance.

Plant it with: Hostas, Siberian bugloss, Hellebores, Epimediums, Japanese forest grass and Snowdrops.

Wildlife: Dense fronds and accumulated leaf litter provide shelter for small garden animals and invertebrates. As a non-flowering plant, it provides no nectar or pollen.

• Brown, crisp fronds: usually caused by dry soil, hot sun or drying wind; water deeply, renew the mulch and provide more shade or shelter.
• Crown rot: waterlogged soil or a buried crown can cause collapse; improve drainage and keep soil and mulch away from the crown.
• Slugs and snails: may damage tender emerging fronds; inspect new growth and use hand-picking or a labelled iron-based bait if needed.
• Winter damage: exposed fronds may flatten or brown after frost; remove damaged foliage before spring growth rather than assuming the plant has died.

Do not eat the fronds, fiddleheads or rhizomes. Dryopteris ferns contain potentially toxic compounds, especially in the rhizomes, and ingestion by people can cause illness or serious poisoning. Species-specific toxicity information for cats, dogs and horses is limited; prevent them from eating it and seek veterinary advice after ingestion.

• Male fern (Dryopteris filix-mas)

  Usually has fewer, paler scales on the frond stems. Golden-scaled male fern has denser golden-brown scales and typically a small dark mark where each main leaflet joins the central stalk.

• Broad buckler fern (Dryopteris dilatata)

  Has broader, more triangular fronds with more finely divided leaflets. Its stem scales commonly have a dark central stripe rather than the more uniformly golden-brown appearance of golden-scaled male fern.

The epithet affinis means 'related' or 'similar', referring to its resemblance to male fern, while golden-scaled describes the scales on its stems and emerging fronds.

Propagation. Divide established clumps with several crowns in spring, keeping roots and a growing point on each division. Single-crowned plants are best left intact. Spores can be sown on moist, sterile compost under cover, but raising plants this way is slow.
