Ferns

POLYPODIUM

Widespread, variable group of ferns. They usually grow in mosses on trees and logs. All have creeping rhizomes and shed spent fronds cleanly as new growth appears.

Polypodium glycyrrhiza

Mat-forming native of coastal regions from Alaska to California. Grows to 1 ft. tall and spreads indefinitely. Use as a groundcover in a woodland or rock garden. Dark green fronds resemble those of a small sword fern (Polystichum). Grow in well-drained soil; mulch with leaf mold or other organic matter. Can take full sun when grown on the coast. Little to regular water.
