There are many forms of the Japanese painted fern, Athyrium nipponicum "Pictum". They have varying degrees of green, dark red, and gray variegation on their fronds and, as a result, they are very popular plants in shade gardens. The variegated holly fern, Arachnoides simplicior variegata, has dark green fonds with a greenish yellow band running along the center of the main vein. The young uncoiling fronds of the autumn fern, Dryopteris erythrosora, are a beautiful bronze color and add color in early spring. The black stems of the maidenhair ferns, Adiantum species, contrast strikingly with the light green fronds. When present, the bright cinnamon-colored, spore-bearing, specialized fronds of the cinnamon fern, Osmunda cinnamomea, stand out against the large green, sterile leafy fronds.
