Dicksonia antarctica, D. sellowiana
The genus Dicksonia includes the most cold-resistant tree ferns in the world.
Despite the name, Dicksonia antarctica isn’t actually found on Antarctica
itself, but in Tasmania and southern Australia. All the same, this fern can even
withstand periods of mild frost, and can be grown outdoors in coastal regions of
Ireland and England. However, smaller plants don’t cope well with ground frost, so
they’re kept indoors until reaching a height of at least one meter.
A very close relative of Dicksonia antarctica is Dicksonia sellowiana,
a native of the montane forests of Central and South America. It grows up to 10 meters
tall and also has a reputation for tolerating cool climatic conditions. Dicksonia sellowiana
is characterized by especially thick coat of fibrous roots on its lower trunk. You can
learn more about the development and uses of this root coat by pressing 345.
