Dicksonia sellowiana was created in 1844.

The Dicksonia tree fern will have brown fronds if they have frostbite. These fronds should be pruned in early spring before the new fronds sprout.

Tree ferns take 5-20 years to mature. After that, they can be quite long-lived in the proper environment. They're found in the tropics and subtropics. The most cold-hardy, and therefore the best known, is the Tasmanian tree fern [Dicksonia antarctica]. It can live some 400 years.
