Ostrich Fern
Deciduous fern reaching 90-150 cm tall. Features large, vase-shaped clumps of sterile fronds and separate, dark brown fertile fronds. Prefers moist, rich soils and partial to full shade. Spreads by underground rhizomes, forming colonies. Provides shelter for wildlife and adds architectural interest to shaded areas. Suitable for woodland gardens, shaded slopes, and naturalized areas in moist sites. Edible fiddleheads in spring.
Plant Details
Bloom Colour: Brown (spores)
Bloom Time: N/A (Fern)
Sun Requirements: Shade to Part-Sun
Moisture: Moist-Drained
Phenology: Fiddleheads emerge late April. Fertile fronds emerge dark brown June. Sterile fronds remain green until frost, then golden brown through winter.
Wildlife Value: Provides cover and nesting sites for ground birds; fiddleheads occasionally eaten by grouse; deer resistant
Habit Over Time: Creates dramatic, vase-shaped clumps that spread steadily through underground runners. New fronds emerge in tight circles, gradually expanding outward from the original planting. While it can spread vigorously in optimal conditions, the colonies maintain a consistent height and can be contained through root barriers. Provides strong architectural interest throughout the growing season.
Height: Tall (3-6 feet)
