Woodwardia unigemmata, commonly known as Jeweled Chain Fern, is an evergreen fern native to the understory of moist forests and along stream banks in South and Southeast Asia, particularly in China. It can grow to a sizeable 1.5 m (4.9 ft) tall by 2.5 m (8.2 ft) broad. The fern is noted for its striking pinnately-divided fronds that emerge with a reddish hue and mature to a lush green. The new fronds’ red coloration adds ornamental interest early in the growing season. Jeweled Chain Fern has received the Royal Horticultural Society’s Award of Garden Merit, indicating its value in cultivation for its aesthetic appeal and performance in gardens.

This fern is valued for its architectural form and the tropical ambiance it brings to garden settings. It is often used in shaded borders, woodland gardens, and as a focal point in moist, shady areas. While it is considered hardy down to −10 °C (14 °F), it requires a sheltered location to protect it from cold winds and harsh conditions. The plant thrives in well-cultivated, reliably moist soil and benefits from a mulch of organic matter to retain moisture. In cultivation, it prefers part shade to full shade and medium amounts of water, with soils that offer slow drainage to maintain consistent moisture. Despite its hardiness, it may suffer from frond damage in harsh winters or if exposed to drying winds.CC BY-SA 4.0
