Blechnum longicauda is a very exotic looking fern from Alexander Selkirk Island in the Juan Fernandez archipelago. The fronds on my ferns habve reached a length of around 60cm. Apparently they reach over 2 metres in their native habitat.
Once you have one plant you will very shortly have plenty more as they are prolific self propagaters iva the bulbils on the tip of the fronds.
Hardiness: Not too sure yet on this fern’s hardiness. The ones I had out during the 2010 winters, made through the first winter in January 2010 but were killed in the December 2010 winter. At a guess they would survive to about a maximum of -5 degrees celsius. Mulch this fern in winter to protect.
