Deer fern

"Blechnum spicant" is a species of fern in the family polypodiaceae, known by the common names hard-fern or deer fern. It is native to Europe and western North America. Like some other "Blechnum" it has two types of leaves. The sterile leaves have flat, wavy-margined leaflets 5 to 8 millimeters wide, while the fertile leaves have much narrower leaflets, each with two thick rows of sori on the underside.

"B. spicant" is hardy and evergreen, growing to 0.5 m. It has gained the Royal Horticultural Society's Award of Garden Merit.
