Dark Light
Christmas Fern
Polystichum acrostichoides

This fern is pretty wide-spread and abundant in eastern deciduous forests. In the spring and summer, the new fronds are very upright. However in the late fall they become horizontal. This movement helps the plant be less exposed to cold, drying winds, and to be closer to warmer soil/ground temperatures.

The warmer winter leaf temperatures promote photosynthetic activity – which is helpful because the Christmas fern remains metabolically active on warm winter days.

Size: 12-24" tall
Family: Dryopteridaceae (Wood Fern Family)
Habitat: Moist to dry forests and woodlands.
Identifiers: Evergreen fern with pinnate fronds from an upright stem. In late fall, the fronds become horizontal, where they remain green until new fronds appear in early spring.

Rock Polypody Fern

No, this is not the band name! (anybody? anybody?) It's a really sweet little fern, and maybe, when it's quiet, you can hear it singing.

Ebony Spleenwort

When I first identified this lil' guy, I was surprised and giddy to hear that it was something called a "spleenwort," rather than a fern.
