Dryopteris xanthomelas, commonly known as Tortoise-Shell Wood Fern, is an evergreen fern native to the understory of temperate forests in the Himalayas, Central and Southeastern China, and Northern Pakistan. It typically grows to a height of 1 foot (0.3 meters) and a width of 2 feet (0.6 meters), featuring arching fronds with a distinctive, scaly appearance that resembles a tortoise shell. The fronds are a rich green color and can add a lush, textured look to shaded garden areas. Flowering is not applicable to ferns, as they reproduce via spores.

Tortoise-Shell Wood Fern is valued for its hardiness and the year-round visual interest it provides in shaded garden spots. It is often used in woodland gardens, shade gardens, and as an understory plant in larger landscapes. It requires consistently moist soil with good organic content and slow drainage, and it thrives in part shade, although it can tolerate more light in cooler climates. While it is not prone to serious diseases or pests, it can suffer from root rot if the soil is too wet. This fern is not known for being invasive and is a good choice for gardeners looking for non-aggressive plants.CC BY-SA 4.0
