Asplenium platyneuron (L.) B.S.P.
Aspleniaceae (Spleenwort Family)
Sterile and fertile fronds are entirely different in appearance and habit. Sterile fronds are only 2-6 in. long, have short, blunt, alternate pinnae,
and are evergreen. Fertile fronds are 1-2 ft. long, erect-arching, and bear short, alternate pinnae
below and longer, opposite pinnae
above. Fronds occur in loose clusters, arising from the clumping rootstock. Colonizing roots are black and wiry.
The word, ebony, refers to the fact that the stalk turns a shining black with age.

Gravelly, slightly acid, well-drained soils. Sandy, Sandy Loam, Medium Loam, Limestone-based. Grows well in acid or alkaline soils. Conditions Comments:
One of the most drought-tolerant ferns, this fern
also takes more sun than many, provided its kept moist enough. Must have good drainage, and does not tolerate flooding. Will need extra water in dry areas to make a ground cover, and even then will only cover loosely.
BenefitUse Ornamental: Good for light, airy cover in drier areas than most ferns can handle.
Interesting Foliage: yes
