Japanese painted fern Interesting Notes

Charming throughout the growing season, Japanese painted fern provides a rare departure from the greens of the shade garden with its seemingly hand-painted, airy fronds. The 12-inch fronds are silvery-gray, almost appearing metallic. But the beautiful garnet-colored veins that extend to the tips of the leaflets really steal the show. Forming a gentle weeping habit, Athyrium niponicum var pictum is a strong growing and dependable plant growing 18” tall and spreading slowly by 24”. In 2004, it was chosen as The Perennial Plant Association's Perennial Plant of the Year®.

Originally native to Japan, Korea, Taiwan and other countries in East Asia, Japanese painted fern prefers evenly moist soils in bright shade. It can take full shade but loses some of its silver and red coloring and can take some sun but direct sunlight will burn the foliage. Athyrium tolerates dry periods after it is established.

Like most Athyriums, Japanese painted ferns are deer and rabbit resistant. The fronds of Athyrium provide nesting habitat for wildlife and is a great groundcover.

A. niponicum is an trouble-free landscape plant that prefers evenly moist soils, but will tolerate long periods of drought once it is established. It is best in partial or full shade. Full sun is possible with ample moisture. Leaves color up more with a bit of sun exposure, but can be more vertical and less attractive if they receive too much sun.
