This fern was introduced to English gardeners in 1852 by Van Houtee, and named in honor of Dr. Von Siebold, who discovered it in Japan. The only other species name that has been used for this fern was the descriptive name D. podophyllum which referred to the fact that the lowest pinnae were stalked.  The bold, halberd-shaped fronds are reminiscent in their general shape and coloration of more tropical species, like Phelbodium pseudoaurem, but with a much greater degree of hardiness.  The broad frond segments have a matte texture and develop a blue-green hue as they mature, making this fern a standout eye-popper in the temperate garden. The prominent mid-veins add further dimension and the numerous sori, randomly scattered on the frond reverse, change from pale green to shiny black as they mature.  The broad fronds make it prone to sunburn, so it is best situated in part shade to full shade.  It performs particularly well in the deep, humid shade of the Southeastern United States and grows faster in warm, shady envrionments.  In cooler climates it is markedly slower, and performs best when given early morning light exposure followed by part shade throughout the day and light, even moisture.
