Blechnum brasiliense 'Volcano' (Brazilian dwarf tree fern)

The Brazilian dwarf tree fern ( Blechnum brasiliense ) remains relatively small, reaching a total height of approximately 120 cm, and is therefore well-suited for indoor cultivation. Unlike species of the genera Cyathea or Dicksonia , Blechnum gibbum and Blechnum brasiliense are not true tree ferns (Cyatheales), but rather the result of convergent evolution. Independently of one another, some hard ferns (Blechnaceae) have also developed a tree-like growth form through their upright rhizomes. Over time, a scaly trunk develops, at the top of which sits the crown of leaves.

Newly emerging leaves are usually rust-red to deep red, depending on the light conditions, which is why it is also known as 'Volcano'. Blechnum brasiliense is significantly less common in the trade than Blechnum gibbum . The species is widespread throughout the South American continent and, according to more recent classifications, is called Neoblechnum brasiliense .
