Giant Chain Fern (Woodwardia fimbriata) is the largest fern in North America, with upright, arching fronds that are wide and lacy. It can reach 3 to 5 feet tall. It will be either evergreen or summer deciduous, depending on its growing conditions.
Giant chain fern prefers part to full shade and likes some moisture but does not want to be kept wet. Allowing it to dry out just a little between waterings is good. It prefers fertile soil with good drainage but is adaptable to different types of soil. To keep it looking fresh and vigorous, cut back to the ground in late winter. Due to its size and shape, it is excellent as an accent in shaded areas or a woodland setting.
