The Japanese Tassel Fern [Polystichum polyblepharum] was the second hardy fern I tried growing in my small Oklahoma City shade garden... and even though my collection now includes nine hardy types of fern it continues to be my favorite. The emerging crosiers are heavily covered with what are correctly called scales... but they really look a lot more like brilliant cinnamon colored fur. As the crosier unfurls it suddenly flips over backwards and forms tassels... hence its name. The maturing fronds extend out from the crown at a fairly shallow angle... giving the plant more a flattened than vase shape. The fronds are dark green and lustrous, with overlapping pinnae. The overall look is very refined and easily distinguished from other hardy ferns.
It is not a difficult fern to grow... even on the Southern Great Plains. It likes rich, organic yet well draining soil and consistent moisture. It also likes protection from our drying southwest winds and shade from noon to 4PM. One special growing tip... you might set the crown at an angle so rain and irrigation water does not accumulate on it and create set-up for crown rot.
