About
Blechnum niponicum forms a nearly horizontal rosette of evergreen fronds that are leathery and robust, displaying a deep green hue. As new fronds emerge, they exhibit subtle tones of pink, red, and orange, particularly at the edges and tips. In summer and autumn, upright spikes that produce fertile spores rise from the center of the plant, contrasting with the surrounding foliage.
About the genus
Blechnum consists primarily of evergreen ferns characterized by upright or spreading rhizomes. The fronds are typically simple and pinnate, with fertile fronds standing upright while the sterile ones tend to spread out.
