An outstanding fern with a large, shuttlecock of bright green fronds, with a black, bristly midrib. It is this feature, and the amazing geometry of the frond structure, that make this fern so exceptional and distinctive.
Although technically evergreen, the leaves always collapse in winter and look better if removed.
Grow in shade in any soil including dry soil.
