Botanical Name: Polystichum acrostichoides pol-ISS-tih-kum ak-roe-stik-OY-deez Common Name: Christmas fern Genus: Polystichum
The Christmas fern is a particularly accommodating garden plant. It is adapted to a wide range of conditions, from very dry to moist, and is hardy to Zone 3. The plant’s 1- to 2-foot fronds are dependably evergreen—hence the common name—but they lie flat on the ground through the winter. Few hardy ferns have more beautiful deep, glossy green foliage.
Noteworthy characteristics: Evergreen; adaptable; glossy foliage.
Care: Very adaptable, but likes full to part shade and fertile, humusy, well-drained soil.
Propagation: Sow spores at 59° to 61°F when ripe. Divide rhizomes in spring. Detach fronds bearing bulbils in autumn.

This fern's lacy foliage smells of freshly mown grass and carpets the woodland or a moist, partially sunny site. The green lushness turns golden in the fall. It is a good choice for rapid naturalizing. Use in a woodland garden or near water features.
