Australian Tree Fern

Alsophila australis

Beautiful, finely cut, broad, bright green fronds spread out from atop a slender trunk, creating a lush and exotic accent with a palm tree-like affect. The fastest growing of the tree ferns and a stunning specimen for adding a tropical element to large containers on patios or indoors, or in temperate landscapes. A frost-tender evergreen.
