Korean Rock Fern

Polystichum tsus-simense

Korean Rock

The Korean rock fern (Polystichum tsus-simense) is a charming low-growing evergreen with a dusky dark green countenance. The rather upright 12″ to 15″ fronds have a prominent contrasting dark stripe up the middle, adding interest to the overall appearance.

This is a species that will do well indoors or out, and is popular for flower arranging (where it will outlive the flowers).

It is closely related to the somewhat taller Polystichum mayebarae and can be grown with it in combo (for your botany class). It is exceptionally garden-worthy in Zones 6 and higher.
