Dicksonia antarctica

Dicksonia antarctica: Characteristics and Care

The Dicksonia antarctica, popularly known as the tree fern, is a tree fern native to Australia and Tasmania, notable for its fibrous trunk formed by intertwined roots and its crown of large, feathery fronds, making it one of the most ancient and sought-after plants for shade gardens.

It is sold as a bare-root trunk, without foliage, which resprouts once planted and regularly watered; its sculptural form and rarity make it a highly coveted piece for exotic and understory gardens.

It requires shade or partial shade and constant environmental and soil humidity; it does not tolerate drought or direct exposure to intense sun.

At Ornacom, we specialize in the import and commercialization of these unique specimens, guaranteeing their proper acclimatization and handling.
