About This Plant
Sphaeropteris cooperi (Australian Tree Fern), 'Australian Tree Fern' is valued in the landscape for character, form, and seasonal interest.
Australian Tree Fern , bold tropical tree fern with broad arching fronds. Spectacular shade specimen in conservatory or summer-patio container.
Part shade suits this species. Plant in moist, well-drained, humus-rich, acidic soil. Hardy USDA Zone 9 to 11. Not winter-hardy outdoors in southern Oregon coast; treat as a summer specimen or conservatory plant. Keep crown moist.
For a Pacific Northwest native tree of similar character, consider Acer macrophyllum (Bigleaf Maple) for canopy, Cornus nuttallii (Pacific Dogwood) for spring bloom, or Arbutus menziesii (Pacific Madrone) for evergreen sculpture and red bark.
