Ostrich Fern

Growing Conditions

Growing Zones

Thrives in USDA Zones 3 - 7

Companion Planting

When to Plant

• Transplant

  Plant divisions or nursery crowns in spring or early autumn in moist, rich soil with partial to full shade

• Harvest

  Harvest fiddleheads when just 2 - 4 inches tall and tightly coiled; rub off the papery brown scales; cook thoroughly before eating - do not eat raw

Organic Growing Tips

• Mulch thickly with leaf litter each autumn to retain the consistent moisture ferns require.

• Never allow the soil to dry out completely; a desiccated crown will produce no fiddleheads the following spring.

• Allow the brown fertile fronds to stand through winter; they are ornamental and mark the crown for spring fiddlehead harvest.

• Plant in drifts along streambanks or pond edges where natural moisture is abundant and maintenance is minimal.

• Divide large clumps every 5 - 7 years in spring; divisions transplant readily and can be used to establish new colonies.

Common Pests

• Slugs
• Deer
• Rust Fungus

Natural History

Matteuccia struthiopteris, the ostrich fern, is a circumboreal species native to cool, moist woodland and streamside habitats across northern North America, Europe, and Asia. In North America its range spans from Newfoundland and Quebec west to British Columbia and south through the northern United States to Missouri and Virginia, always in association with moist, rich soils near streams and in floodplain forests. The common name refers to the resemblance of the large, arching sterile fronds to the plumes of an ostrich. The harvest of fiddleheads - the tightly coiled young fronds in their first few inches of emergence - as a spring vegetable has been practiced by many Indigenous nations of northeastern North America, including the Mi'kmaq, Maliseet, Abenaki, and Haudenosaunee, for whom the brief fiddlehead season represented one of the first fresh vegetables of spring after winter. In Atlantic Canada and the northeastern United States, fiddlehead harvesting remains a deeply embedded seasonal food tradition: spring markets in New Brunswick, Nova Scotia, and Quebec still feature fresh fiddleheads prominently, and the fiddlehead season of 2 - 4 weeks each year is treated as a culinary event. A 1994 outbreak of food poisoning in the United States and Canada linked to raw and undercooked fiddleheads led to public health guidance that fiddleheads must be boiled or steamed for 10 - 15 minutes before eating - a recommendation that amended older traditions of light cooking or raw consumption. Modern research has confirmed that thorough cooking eliminates the compounds responsible for illness, and properly cooked ostrich fern fiddleheads are considered safe.

Traditional Use

Ostrich fern was used primarily as a food plant by the Indigenous peoples of northeastern North America, with only limited medicinal applications recorded. The Mi'kmaq and Maliseet ethnobotanical records note fiddlehead use as a seasonal food, and some traditions used the fronds in preparations for minor skin and rheumatic complaints. The dominant tradition is culinary rather than medicinal, and this reflects the plant's main cultural role as a valuable seasonal food source.

• Mi'kmaq and Maliseet peoples, Atlantic Canada, pre-colonial through 19th century - Fiddleheads

  Ethnobotanical records document ostrich fern fiddleheads as an important early-spring food among Mi'kmaq and Maliseet communities of Atlantic Canada and northern New England. The brief spring emergence of fiddleheads was recognized as one of the first significant fresh foods after winter, and large quantities were gathered, eaten fresh, and preserved by drying for later use.

• Abenaki and Haudenosaunee peoples, northeastern North America - Fiddleheads and rhizome

  Records describe fiddlehead gathering as a spring activity and the rhizome as having been used in occasional preparations for skin conditions and joint pain, consistent with the broader pattern of using fern rhizomes in topical applications in Indigenous northeastern woodland medicine.

Ostrich fern fiddleheads must be thoroughly cooked before eating - boiling or steaming for 10 - 15 minutes is required. Raw and undercooked fiddleheads have caused documented food poisoning outbreaks. Do not eat them raw, lightly sauteed from raw, or in preparations where they have not been fully pre-cooked first. Identification is also critical: only Matteuccia struthiopteris fiddleheads are considered safe; other fern species should not be eaten as fiddleheads.

Morphology (Plant Structure & Identification)

• Root System

  Stout, upright rhizome crown producing horizontal underground stolons that generate new crowns, slowly spreading into colonies; roots are dense and fibrous, adapted to moist streamside conditions.

• Stem

  No true stem; fronds emerge directly from the crown. Two types of fronds are produced: large arching bright green sterile fronds in a vase shape, and shorter, erect dark brown fertile fronds that persist through winter and hold the spores.

• Leaves

  Sterile fronds 2 - 5 feet tall, pinnately compound, bright green, broadest in the upper third and tapering to a point - the ostrich plume shape; fertile fronds shorter, dark brown, stiff, and erect, with tightly rolled leaflets enclosing the spore cases.

• Flowers

  Ferns do not produce flowers; reproduction is by spores released from the fertile fronds in autumn.

• Fruit

  No fruit; spore capsules (sori) are enclosed within the rolled fertile frond leaflets and released as dust-fine brown spores in autumn and winter.

Known Varieties

Common cultivars worth knowing

• Straight Species

  The native species; extremely variable in size across populations, with plants in ideal moist conditions reaching 5 feet and compact forms in drier sites staying at 2 - 3 feet. No named cultivars in common use.
