Ebony Spleenwort (Asplenium platyneuron)


Sterile and fertile fronds are entirely different in appearance and habit. Sterile fronds are only 2-6 in. long, have short, blunt, alternatepinnae, and are evergreen. Fertile fronds are 1-2 ft. long, erect-arching, and bear short, alternate pinnae below and longer, oppositepinnae above. Fronds occur in loose clusters, arising from the clumping rootstock. Colonizing roots are black and wiry.
