Narrow Golden Scaled Male Fern (Dryopteris cambrensis)

8.00

The male fern complex in England comprising what was most recently the Dryopteris affinis group has been reclassified again according to laboratory evaluation. Although the divisons into separately recognized species and subspecies is based on field keys as to the range of frond shape, teeth and lobed pinna segments, indusium maturation, and degress of scaliness there is a lot of natural variation within each species and some characters overlap in extreme environments. Some current catalog offerings seem to believe that the subspecies designation indicates that this is a cultivar. Looking up proper nomenclature and spelling for ferns does not seem to be a factor in most catalog and website offerings. I have even seen subsp. cambrensis described as a crested form. The texture of the foliage is firm and leathery but only slightly glossy as compared to subspecies affinis. The pinnae are held at a very slight angle to the plane of the blade especially in exposed sites giving this type a somewhat layered look. The overall blade is narrowly elliptical with the pinnae oblong to triangular finishing off with a long acuminate apex. Reddish gold scales densely clothe the stipe.  The epithet cambrensis has been mis-applied as a cultivar name. One web site even claims that this species once considered to be a subpecies of affinis denotes a crested form. Since very few nurseries in the US are capable of keying out this complex I have no idea what they are selling under this name!  Anyway, we love these because they are vigorous, fast growing, hardy and reliable and we have had great success with them in our woodland garden.
