Guide

The species-level account. Cultivar pages build on this and say where they differ.

Blechnum gibbum is a fern in the Blechnaceae, a family of moisture-loving plants that keep evenly damp but never sit in standing water. Give it bright indirect light out of direct sun, and water when the top of the mix feels barely dry to the touch, aiming to keep it lightly moist rather than soggy. Ferns of this kind favour higher humidity, so it will hold better away from dry heat and drafts.
