Brazilian Tree Fern: a striking, formal looking, mostly solitary, rosette-forming species that can develop a short trunk with age. It is most recognizable by its deep bronze-red new fronds, which are produced in flushes, which age to a glossy dark green. The sword-like fronds reach about 2' and are usually rather upright, forming a vase shape and getting to about 5' tall. It needs frost protection and should be sited where it won't get a severe freeze if possible.
