Ostrich ferns feature erect divided and lance-shaped fronds that arch gracefully outwards into a symmetric clump. They are dramatic for foliage backdrops, foundation and boundary plantings, naturalizing and fresh arrangements.

It grows from a completely vertical crown but sends out lateral stolons to form new crowns. It thus can form dense colonies resistant to destruction by floodwaters.

Ostrich ferns require moist soil, especially in hot, dry climates (the more moisture, the larger the plant). It does best if planted in partial shade, in a deep loamy mix enriched with plenty of organic matter but can also grow in heavy clay soil. Mulch lightly with leaves around the slightly exposed crown, and in no time, a beautiful fern thicket will be sprouting lush growth.

It is winter dormant, growth rate is moderate. However, under good conditions it tends to spread aggressively by stout rhizomes. The edible tightly wound immature frond (called fiddleheads) appearing in spring are a delicacy and - as the state vegetable of Vermont - are considered a delicacy.
