Asplenium nidus, commonly called Asplenium Crispy Wave, is a slow-growing, epiphytic fern of the spleenwort family featuring simple, entire, strap-shaped, glossy, bright apple green fronds with contrasting dark brown to black midribs and undulating margins. Fronds spread upward and outward to form a vase-shaped, green rosette with a nest-like center into which fallen leaves and other organic matter typically accumulate. Mature fronds on outdoor plants grow to as much as 4-5’ long with a spread to 8” wide, but fronds on indoor container plants typically grow to only 1 1/2′ to 2’ long.
Planting & Caring –
Easily grown outside in the ground in warm, bright but shady locations in humus-rich, moist but well-drained soils with added leaf mold, sand, and grit. Avoid direct sun. Ferns grown outside prefer minimum temperatures of 50 degrees F., but will usually tolerate occasional brief temperature dips into the high 30s.
