Dryopteris crassirhizoma Giant Plants As they are attached to(syn: Dryopteris buschiana) Dryopteris crassirhizoma is a handsome, tall, Clark Gablesque, vase shaped fern that usually forms a solitary crown and can reach 3' tall x 3' wide when happy. The semi evergreen, deer resistant, thick textured fronds of Dryopteris crassirhizoma give a very tropical appearance in the garden. In winter, the fronds remain green but lay flat on the ground, helping to protect those nearby from the ravages of winter.
