Crested Japanese Painted Fern

Athyrium niponicum ‘Crested Surf’ is a Japanese painted fern selected for its stiff, upright fronds with distinctive double-crested tips. Its green and silver foliage and wine-colored stems give a shaded border a more sculptural texture than ordinary painted fern; these traits are described by [Walters Gardens](https://www.waltersgardens.com/variety.php?ID=ATHCS). ## Cultivar and size Walters Gardens introduced this patented selection. Mature plants are listed at 20–22 inches tall and 28–30 inches wide, with USDA hardiness in zones 3–8. The [patent](https://patents.google.com/patent/USPP33057P2/en) documents the same cultivar, its branched cresting, green leaf pattern, and wine-toned petioles and midribs. Its three-year shaded trial plant reached about 60 cm tall by 112 cm wide, illustrating how age and growing conditions can produce a larger spread than the nursery profile. ## Siting Grow in part shade to full shade in consistently moist, fertile soil that drains well. Walters Gardens lists neutral to moderately acidic conditions as suitable. Shelter the crown from drying exposure, and keep the root zone evenly moist during establishment and dry spells. It forms a clumping mound rather than a fast groundcover. ## Landscape use Set it in the middle of a shaded border, woodland garden, or a roomy container. The double crests are easiest to appreciate where the fronds are viewed at close range. Ferns produce spores rather than flowers. ## Maintenance Leave the previous season’s fronds in place through winter. In spring, remove them after new fronds have grown to about six inches. Divide in spring only if a mature clump needs renewal or propagation.
