Asplenium platyneuronAlso known as:
Asplenium platyneuron is the largest of spleenworts, with semi-evergreen fertile fronds up to 1 1/2' long, and shorter evergreen sterile fronds that are 2 to 6" long. Leaflets are dark green, and the stipe (central stem) is glossy and deep purple to brown. This is a very elegant fern that forms open, asymmetrical clumps.
Ebony spleenwort is the most adaptable fern in the genus. As other spleenworts, it grows well in rock walls and crevices, but this one is very easy to grow in terrestrial garden conditions. The preference is part-sun or dappled light, and moist to dry well-drained soil. Over watering this fern can lead to crown rot. Zones 4-10
Will spread by spores under ideal conditions, but is more easily propagated by rhizome cuttings.
Although the stipes are very dark, the common name 'ebony spleenwort' refers to its black fibrous roots. Can be confused with Polystichum acrostichoides (Christmas fern).
