Dryopteridaceae (Wood Indies-Almond Family)



Polystichum acrostichoides (Christmas fern)
Wasowski, Sally and Andy
Chistmas fern got its name because it stays green right through the holiday season. It is a robust, leathery fern which has glossy, green fronds year-round. The fronds grow in clusters from a crownless rootstock and range from 1-2 ft. in length. Fertile fronds are taller. The once-divided fronds with pointed pinnae result in a medium to coarse texture. The silvery fiddleheads emerge in early spring.

Christmas fern is very easy to establish and grow where conditions are right. It requires cool, moist, well-drained soil in shade. In the right spot, it can be a good, evergreen border or accent plant. Though often used as a groundcover, it is a clumping fern, not forming a continuous, undifferentiated carpet the way some ferns do.
