Summary
Polystichum neolobatum, commonly known as Asian Saber Fern, is an evergreen fern native to the understory of temperate forests in East Asia, particularly in regions of China, Japan, and Taiwan. It typically grows to a height and width of 1-3 feet (0.3-0.9 meters), featuring glossy, dark green fronds that have a sword-like appearance and are arranged in an attractive, arching rosette. The fronds are bi-pinnate, giving them a feathery texture, and they can add a lush, tropical feel to garden settings.
Asian Saber Fern is appreciated for its year-round foliage and its ability to thrive in shaded conditions, making it an excellent choice for woodland gardens, shaded borders, or as an understory plant in shaded areas of the landscape. It is also suitable for container planting, where its evergreen nature can be enjoyed up close. This fern prefers consistently moist, well-drained soil that is rich in organic matter. While it is relatively low maintenance, it benefits from the removal of old fronds to maintain a tidy appearance. It is not known to have serious disease or pest problems, but it can suffer from root rot if the soil is too wet.CC BY-SA 4.0
