Habitat Notes

General Notes
For further details of propagating from spores see C. cunninghamii. Readily re-establishes from spores in regenerating logged sites and in other disturbed but sheltered, moist clayey soils, receiving ample light. Very adaptable, tolerating a range of conditions from wet soils to dry situations. Will withstand more sun than most species. Immature fronds may be burnt by frost, but are quickly replaced by new fronds in spring. Not suitable below powerlines.
