This delicate pale green fern with black veins in the unique finger shaped fronds adds a distinct character to the canyon at Silver Falls. Look for these ferns growing on the rocks behind the waterfalls and lining the canyon walls. This dainty fern likes to grow in rock crevices and in constant mist produced by flowing water.
The number of “fingers” (fronds) determines specie differences.
