Japanese Holly Hardy Ferns add interesting texture to a garden with its dark green foliage. This type of fern grows in a mound that can reach 1-2 feet high and 2-3 feet wide. Other ferns have delicate fronds but the Japanese Holly has holly-like leaflets called pinnae that are leathery. These fronds (stems and leaves) are tough and resilient. Spores adhere to the undersides of each leaflet. They are green when young and turn dark when mature. To keep your fern looking good, trim ragged fronds back to about 1-2 inches above the crown. Trimming too close could damage the crown. Make sure that the soil drains well to prevent root rot.
