About this cultivar:
Dryopteris crassirhizoma (syn: Dryopteris buschiana) is a handsome, tall, vase-shaped fern that usually forms a solitary crown. The thick textured fronds of Dryopteris crassirhizoma give a very tropical appearance in the garden. It gets its name from the Latin 'Crassus' (thick) and the Greek 'rhizoma' (mass of roots). But remember that a rhizome is an underground stem.....

About this genus:
Dryopteris is a fern genus of 225 species from around the world that give us the majority of our great garden ferns. The genus name comes from the Greek words drys (tree) and pteris (fern) in possible reference to this fern's typical habitat in woodland areas. It is a good idea to put Dryopteris (male ferns) near Athyriums (lady ferns) for reasons that (I hope) are obvious.
Dryopteris species come in a variety of shapes and sizes. Most gardeners assume that all ferns are green but Dryopteris species have variation in that regard - which ironically makes many people think they a dying or drying out! - once a week I have a customer telling me they need watered! The new growth on some species may be copper or cinnamon or even black.
Like most garden ferns, Dryopteris plants prefer light shade, almost full shade. Soil wise - anything that isn't too extreme. How to use them? Well... try shady areas!
