About Tasmanian Tree Fern
Dicksonia antarctica, the soft tree fern, is a slow-growing arborescent fern native to southeastern Australia and Tasmania, developing a fibrous trunk topped with a spreading crown of large, finely divided fronds. One of the most architecturally striking ferns available, it is prized as a specimen plant in sheltered, humid gardens. Starting at $75.95.

Care essentials
Plant in part shade to full shade with protection from direct afternoon sun and strong winds; a dappled canopy or north/east-facing exposure works well in NE Florida.
Keep the soil consistently moist and hose down the fibrous trunk daily during hot, dry spells; this fern resents drought but requires well-drained soil to prevent root rot.
Plant in humus-rich, organically amended, well-drained soil with acidic pH; incorporate compost at planting and mulch heavily to retain moisture and protect the base of the trunk.
