Overview

The Japanese painted fern (Athyrium niponicum var. pictum) is a deciduous perennial fern renowned for its strikingly colored fronds—metallic silver-gray overlaid with burgundy veins and flushed with hints of green. Each arching frond reaches 12–18 inches, forming a graceful, vase-shaped clump 18–24 inches wide. It brings sophisticated, season-long color to shady borders, woodland gardens, and container plantings.

Why Gardeners Love It
