Adiantum hispidulum

Grown from short, creeping rhizomes, Adiantum hispidulum forms graceful clumps of fan-shaped, upright fronds rising a compact 12–18 inches tall and wide, maturing over a few seasons. In early spring, these fronds emerge with a rosy-pink whisper, before deepening to bronzy green as they unfurl—a visual poem to sunrise in your shaded borders. Known as the Rough Maidenhair or Five-finger Jack, this fern’s dark wiry stems bear a delicate covering of hairs—nature’s own embroidery on its hardwood fern form. Native to warm regions of Africa, Australia, Asia, and the Pacific, it’s become a trusted garden companion in USDA Zones 8–10, even naturalizing in parts of Zone 9. It thrives in moist, humus-rich soil, sheltered shade, and appreciates a touch of lime or crushed oyster shell—then a winter mulch, so it may return each spring as a rustled blush in the understory .
