Sm. }} Blechnum spicant is a species of fern in the family Blechnaceae, known by the common names hard-fern[1] 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. The Latin specific epithet spicant is of uncertain origin, possibly referring to a tufted or spiky habit.[2] B. spicant is hardy down to {{convert|-20|C|F}} and evergreen, growing to {{convert|0.5|m|abbr=on}}.[3] It has gained the Royal Horticultural Society's Award of Garden Merit.[4]See also
