Plant Biography

Grows best in indirect light and is quite tolerant of shady positions. The creeping rhizomes will quickly fill the pot and provide a dense crown of arching fronds.

Care & Size Guidance

Care & Size Guidance

You’ll need a large space to appreciate this fern in all of its glory. Best displayed in a hanging basket, or on top of a pedestal so that the crown can hang down without impediment.

If the Giant Sword Fern gets too large, the rootball can be divided into smaller plants.

Feed regularly with a fern fertiliser from April to September.
