About

Dryopteris filix-mas, the male fern, is a common fern of the temperate Northern Hemisphere, native to much of Europe, Asia, and North America. It favours damp shaded areas in the understory of woodlands, but also shady places on hedge-banks, and rocks, and screes. Near the northern limit of its distribution it prefers sunny, well-drained sites. It is much less abundant in North America than in Europe.

How to grow it

Numerous cultivars have been selected for garden use. The following have gained the Royal Horticultural Society's Award of Garden Merit:

D. filix-mas

Safety

The rhizomes of D. filix-mas are toxic. Doses too big can cause serious poisoning, blindness and even death.
