P. acrostichoides – Christmas Fern – This terrestrial, evergreen fern from Northeastern North America grows 18-30″ tall and 36″ wide. It produces shuttlecock of narrowly lance shaped, pinnate, dark green, leathery fronds, 24″ long, with small pinnae. Fronds emerge silvery white and mature to dark green. Fertile fronds narrow abruptly toward the tips where the sori occur.
Grow in fertile, humus rich, well drained soil in deep or partial shade. Remove dead fronds before new ones unfurl. Divide in spring.
