Ebony spleenwort is a delicate native fern that brings understated elegance to shaded garden corners. This evergreen Missouri native grows 6 to 12 inches tall and wide, with arching, pinnate fronds in dark glossy green topped by more upright fertile fronds distinguished by their dark purplish-brown stems. Hardy in zones 3 through 8, it thrives in partial shade and tolerates full shade beautifully, making it one of the most adaptable ferns for challenging woodland conditions. Its drought tolerance and ability to flourish in rocky, well-drained soils mean once established, it asks little of you.

The ebony spleenwort's dark purplish-brown stems and glossy, arching fronds create a subtle textural contrast that catches light beautifully in shade gardens. It's a true native performer that actually prefers lean, gritty soils and poor drainage resistance, thriving in the exact rocky slopes and mossy banks where other ferns struggle. For gardeners tired of coddling plants, this fern rewards honest neglect and rocky sites with vigorous, unfussy growth.
Ebony spleenwort serves primarily as an ornamental fern for woodland gardens, rock gardens, and shaded landscapes. Its compact size and tolerant nature make it valuable for stabilizing rocky banks and adding fine texture to shade borders where few other plants will thrive.

“Ebony spleenwort is a native fern found naturally on rocky wooded ledges, slopes, and mossy banks throughout Missouri and beyond. The genus name Asplenium derives from ancient Greek, originally connected to the belief that certain species in this genus could treat ailments of the spleen, though modern gardeners simply appreciate it for its ornamental grace and hardy constitution.”
