Phyllitis scolopendrium ‘Undulata’ is considered a perennial evergreen fern here in Tennessee - displaying erect, arching clumps of lovely, uncut, strap-like fronds with wavy margins. We also sell quite a few of these for houseplants. These deep green, 3″ wide fronds turn chartreuse when backlit by the sun. At maturity, this fern reaches 15" tall and 2' wide.
