Why Grow Ferns

Ferns are among the oldest plants on Earth, and their timeless beauty solves one of gardening's biggest challenges: what to plant in deep shade. Their delicate, intricate fronds create textures that no flowering plant can match. A mass of ferns under trees transforms a bare, problem area into a lush, cool, inviting woodland scene.

Best Garden Ferns

Autumn fern (Dryopteris erythrosora) emerges copper-colored and is semi-evergreen. Japanese painted fern (Athyrium niponicum 'Pictum') offers silver and purple fronds — the showiest fern. Maidenhair fern (Adiantum) has delicate, fan-shaped leaflets on black stems. Ostrich fern (Matteuccia) produces dramatic 4-foot vase-shaped fronds. Christmas fern (Polystichum) is evergreen and native.

Creating a Fern Garden

Mass a single fern variety for maximum impact — 20 ostrich ferns under a tree canopy creates a breathtaking scene. Combine fern textures: bold ostrich ferns with delicate maidenhairs. Pair with hostas for contrasting leaf shapes. Add moss-covered stones for a naturalistic woodland floor. Ferns look beautiful edging a shaded pathway or surrounding a water feature.

Care and Growing

Ferns need consistent moisture and rich, humus-y soil. Mulch with leaf mold or composted bark to mimic the forest floor. Most ferns prefer shade but tolerate morning sun. Cut back deciduous ferns in late winter before new fiddleheads emerge. Divide crowded clumps in spring. Avoid planting in windy, exposed locations — delicate fronds dry out and burn in wind.

Frequently Asked Questions

Are ferns hard to grow?

Ferns are easy in the right conditions: shade, consistent moisture, and rich soil. If you have these three things, ferns practically grow themselves. They fail in sun, dry soil, or wind.

Do ferns come back every year?

Hardy garden ferns are perennials that return every spring. Some (Christmas fern, autumn fern) are evergreen. Tropical ferns used as houseplants are not frost-hardy outdoors.

Can ferns grow indoors?

Boston ferns, maidenhair ferns, and bird's nest ferns are excellent houseplants. They need indirect light and high humidity. Mist regularly or place on a pebble tray with water.
