Neoblechnum is a genus of ferns in the family Blechnaceae, subfamily Blechnoideae, with a single species Neoblechnum brasiliense, according to the Pteridophyte Phylogeny Group classification of 2016 (PPG I).[1] The genus is accepted in a 2016 classification of the family Blechnaceae,[3] but other sources sink it into a very broadly defined Blechnum, equivalent to the whole of the PPG I subfamily;[4] the species is then known as Blechnum brasiliense. It is called Brazilian dwarf tree fern, red Brazilian tree fern, and red dwarf tree fern.[5][6]

Description

The erect rhizome of Neoblechnum brasiliense forms a thin stipe-stubbed trunk up to 30 centimetres (12 in) in height. The new foliage is a striking deep red color. As the fronds mature it turns to a glossy green.[7] On some selections, the new fronds emerge a pinkish-red.

Distribution

The fern is native to the warm and humid subtropical forests of South America.[7]

Habitats include:[5]

Cultivation

Neoblechnum brasiliense is cultivated as an ornamental plant.[7] In the UK (under the synonym Blechnum brasiliense) it has gained the Royal Horticultural Society's Award of Garden Merit.[8] As it will not tolerate temperatures below 15 °C (59 °F) it must be grown under glass all year in temperate regions.

Cultivars

Named cultivars include:

  • 'Crispum' — segments have prominently crisped margins[7][9]
  • 'Cristatum' — segments are crested[7]
  • 'Volcano' — red dwarf tree fern, new foliage is red[10]
