Comments: It is unsure where the common name has come from but it is thought that it is derived from it being evergreen during Christmas.
Etymology: The name Polystichum comes from the greek words, poly and stichos meaning "many rows" referring to its sori. The specific epithet refers to the resemblance of the fern to a tropical fern called Acrostichum. The Latin word -oides means "looks like".
Landscape: As a gorgeous fern, it fulfills the landscape need of shade tolerant plants as well as a smaller size. The glossy green color holds throughout the winter.
