Australian Tree Fern

Australian Tree Fern (Cyathea cooperi)

Australian Tree Fern is a fast-growing tropical fern with a slender trunk and a wide crown of arching fronds, creating instant canopy and lush, prehistoric appeal for shaded gardens, patios, and bright indoor atriums in large containers.

Distinctive Features

Feathery fronds radiate from a shaggy, textured crown atop a single trunk, delivering bold vertical structure and dappled shade; thrives in warm, humid, wind-sheltered sites with steady moisture.

Growing Conditions

• Sun Exposure: Bright, indirect light to dappled shade; avoid harsh midday sun and drying winds.
• Soil: Rich, well-drained, high-organic mix that holds moisture yet stays airy.
• Water: Keep evenly moist; do not allow the root zone or crown to fully dry.
• USDA Hardiness Zones: 9 to 11 outdoors; grow in containers and overwinter indoors in cooler regions.
• Humidity: Medium to high; mist in dry climates for best frond quality.
• Mature Size: Outdoors 15 to 30 ft tall with 6 to 12 ft fronds; 6 to 10 ft in large containers.
• Soil pH: Slightly acidic to neutral, about 6.0 to 7.0.

Ideal Uses

• Focal Point: Dramatic trunk and sweeping fronds create a living centerpiece in shaded courtyards.
• Tropical Shade Garden: Provides light canopy over ferns, caladiums, and hostas.
• Patio Container: Thrives in large tubs with regular water and protection from wind.
• Understory Accent: Layers texture beneath taller trees in frost-free landscapes.

Low Maintenance Care

• Watering: Water deeply when the top inch is barely dry; increase frequency in heat and wind.
• Pruning: Remove spent fronds at the base; never cut into the crown where new fronds emerge.
• Fertilizing: Feed at half strength every 4 to 6 weeks in spring and summer for vigorous frond growth.
• Mulching: Apply 2 to 3 in of fine bark or leaf mold to conserve moisture and enrich soil.
• Notes: Protect from frost and strong winds; keep the crown slightly elevated and avoid waterlogging.
