Notes
Korean rock fern (Polystichum tsussimense) is an evergreen fern for borders, containers, and low maintenance gardens. It is hardy to USDA zone 6, or down to -10°F (-23°C). This plant likes part sun to full shade and average to moist soil of most types. It grows 12 to 24 inches tall and wide, so it fits small spaces. The fronds stay green through winter and give you color when other plants fade.
Pairs well with Lady fern, Blue flag, Climbing hydrangea, and Snake's head.
Native range
Central America, South America, and Panamá.
