Braum's Holly Fern

Polystichum braunii (pol-IS-tick-um BRAUN-ee-eye)

Family: Polypodiaceae Unknown Herbaceous (1-3 ft)

Braum's Holly Fern is a creeping, crown-forming rhizome in the wood fern family (Polypodiaceae) native to Eurasia and North America. It prefers moist, humus rich soil but tolerates dry soil after established. It also prefers cool temperatures. This plant is seldom damaged by deer. This fern has a wide, arching vase of lustrous, bipinnate dark green, leathery fronds. The blade tapers to the base. It has 20 to 40 pairs of closely spaced pinna and 16 to 18 pairs of closely spaced, bristle-toothed, oblong or ovate pinnules. The lower pinnules hug the rachis. The stipe, rachis, and fiddlehead have dense covering of silvery scales, that when mature turn brown. Insects, Diseases, and Other Plant Problems: Crown rot is possible in poorly drained soil.
