Goldie's wood fern

Sun

Partial to full shade; avoid hot afternoon sun.

Water

Keep evenly moist, especially during establishment and summer heat; avoid prolonged waterlogging.

Soil

Deep, humus-rich, well-drained soil, preferably slightly acidic to neutral; tolerates some alkalinity.

Height

3-4 ft (0.9-1.2 m)

Spread

3-5 ft (0.9-1.5 m)

Foliage

Broad, arching, twice-divided green fronds with a somewhat golden-green cast when young. Small, round spore clusters develop beneath mature fronds.

Growth

Slow to moderate; takes several years to form a substantial clump.

Cats and dogs

Mildly toxic: may upset a stomach

Growth rate

Slow

• Water deeply during dry spells so the root zone stays moist.
• Apply leaf mould or well-rotted compost each spring; routine fertilizer is usually unnecessary.
• Maintain a 2-3 in (5-8 cm) organic mulch, keeping it clear of the crown.
• Shelter from drying winds and strong afternoon sun.
• Divide only when necessary, in early spring before the fronds unfurl.

Pruning. Cut dead fronds back near ground level in late winter or early spring before new growth emerges. Leave healthy green fronds intact through the growing season.

Late winter

Remove collapsed, dead fronds before new growth begins.

Early spring

Plant or divide while dormant, keeping the crown at its previous soil level.

Spring

Top-dress with leaf mould or compost and renew mulch without burying the crown.

Late spring

Check emerging fronds for slug and snail damage.

Summer

Water during dry periods and watch for scorched or wilting fronds.

Autumn

Leave healthy fronds to die back naturally and retain a loose layer of fallen leaves around the clump.

• Use as a large foliage anchor beneath deciduous trees where soil remains moist.
• Group with smaller ferns and woodland groundcovers to create layers of contrasting foliage.
• Plant behind hostas or foamflowers in a shaded border for height and texture.
• Place beside a shaded path or seating area where its arching fronds have room to spread.

Garden styles it suits: Woodland, Green on green, Secret garden, English country and Wildlife garden.

Plant it with: Hostas, Foamflowers, Solomon's seal, Wild ginger, Astilbes and Japanese painted fern.

Wildlife: Dense clumps and surrounding leaf litter provide shelter for small woodland animals and invertebrates. It has no flowers or nectar and is generally little browsed by deer, though not deer-proof.

• Dry soil or hot sun causes brown edges and early dieback: water deeply, mulch and provide more shade.
• Slugs and snails can damage emerging fronds: inspect at dusk, remove pests and use a labelled iron-phosphate bait if needed.
• Persistent waterlogging can rot the crown: improve drainage or move the plant to moist but aerated soil.
• Drying winds can shred or scorch fronds: provide shelter and maintain soil moisture.

Toxicity to cats, dogs, horses and people is not well established for this species. Related wood ferns contain toxins, especially in their rhizomes, so do not eat the fronds or underground parts or allow animals to graze them; the severity of poisoning from this species is uncertain.

• Male fern (Dryopteris filix-mas)

  Usually has narrower, more lance-shaped fronds; Goldie's wood fern has notably broad, oval fronds with large lower leaflets.

• Marginal wood fern (Dryopteris marginalis)

  Has leathery, evergreen fronds and spore clusters close to the leaflet margins; Goldie's is deciduous, with spore clusters farther inward.

• Ostrich fern (Matteuccia struthiopteris)

  Has strongly tapered, feather-shaped fronds and separate, narrow brown fertile fronds. Goldie's bears spores beneath its ordinary green fronds and forms a more restrained clump.

The names goldiana and Goldie's fern honour Scottish botanist John Goldie, while Dryopteris comes from Greek words associated with oak and fern.

Propagation. Divide established clumps in early spring, retaining healthy roots and growing points on each piece. It can also be raised from spores, but this is slow and requires clean, consistently humid conditions.

Accepted botanical name

Dryopteris goeldiana Dryopteris goldiana is an older name for Dryopteris goeldiana.
