Dryopteris crassirhizoma

Thick Stemmed Wood Fern

Categories: Ferns

As the common name suggests, it is noted for massive caudex (crown or woody base) that is covered with long brown scales. Fronds grow upward from the outside of the crown usually producing a symmetrical vase of greenery. In cold winters, fronds remain green but recline to spread flat along the ground.
