Polystichum retrosopaleaceum, commonly known as Narrow Tassel Fern, is an evergreen fern native to the understory of temperate forests and shaded mountainous regions in East Asia, including countries like Japan, China, and Korea. It typically grows to a height and width of 2-3 feet (0.6-0.9 meters), featuring arching fronds with a delicate, feathery appearance. The fronds are dark green with a glossy finish, contributing to the plant’s ornamental value. The Narrow Tassel Fern does not produce flowers but is valued for its evergreen foliage that provides year-round interest in the garden.

This fern is appreciated for its ease of maintenance and suitability for shaded garden areas where other plants may struggle. It is often used in woodland gardens, shade gardens, and as an understory plant in larger landscapes. The Narrow Tassel Fern thrives in humus-rich, well-drained soil and prefers consistent moisture without waterlogging. It is relatively pest and disease-free but can occasionally suffer from root rot if drainage is poor.CC BY-SA 4.0
