Report an issue with this species
Dicksonia antarctica is a robust, attractive tree fern native to eastern Australia, characterized by a thick, fibrous trunk and a large, spreading crown of dark green fronds. It typically dominates wet, shady gullies and serves as a keystone species, providing habitat for other plants and wildlife. While popular in cultivation in temperate regions, it is slow-growing and requires consistently moist conditions, tolerating some frost and shade but susceptible to drought.
