Dryopteris crassirhizoma: Thick-stemmed Wood Fern

Dryopteris crassirhizoma, the Thick-stemmed Wood Fern, is a robust, evergreen fern native to East Asia. It forms a large, erect clump with a distinctively thick, woody, creeping rhizome (often above ground). The fronds are bipinnate, leathery, dark green, and up to 3-4 feet tall. The stipes are densely scaly. It has a very sturdy, architectural habit.

Plant Profile

This fern prefers partial to full shade and moist, well-drained, humus-rich soil. The thick, woody rhizome is a distinctive feature, often forming a prostrate trunk. It is a bold, structural plant for woodland gardens, shaded slopes, and as a specimen. Very long-lived and imposing. A great choice for a "fern tree" effect without the height.
