Adiantum chilense var. sulphureum, commonly known as Maidenhair Fern, is a semi-deciduous fern native to the temperate rainforests and streambanks of Southern South America, particularly in Chile and Argentina. It typically grows to a height and width of 2-3 feet (0.6-0.9 meters), featuring delicate, fan-shaped fronds with small, rounded leaflets on wiry, black stems. The fronds are light green, adding a soft texture to shaded garden areas. Flowering is not applicable to ferns, but the graceful form of the fronds provides visual interest throughout the growing season.

Maidenhair Fern is appreciated for its airy foliage and is often used in shaded garden beds, woodland gardens, and as a container plant for shaded patios. It thrives in moist, well-drained, humus-rich soil and benefits from regular watering, especially during dry periods. While it prefers part shade, it can tolerate more sun if kept consistently moist. This fern is relatively low maintenance but may require protection from harsh sun and strong winds. It is not known for serious disease or pest problems, but it can suffer from root rot if overwatered or planted in poorly drained soils.CC BY-SA 4.0
