|Blechnum brasiliense (Brazilian dwarf tree fern). The plant's rhizome forms a thin, stipe-stubbed trunk measuring up to 30 centimetres tall. Fronds are initially a deep red colour, but turn to glossy green as they mature. The Brazilian dwarf tree fern is native to the warm and humid subtropical forests of South America and is cultivated as an ornamental plant. As it cannot tolerate temperatures below 15 degrees centigrade, it must be kept in glasshouses year-round if grown outside subtropical regions.|
