Japanese Painted Fern
The Classic Silver-and-Burgundy Fern for Minnesota Shade
Japanese Painted Fern (Athyrium niponicum var. pictum) is the most beloved colored fern in the shade garden — arching, metallic-silver fronds brushed with soft burgundy and gray-green, on a tidy, compact clump. Its painterly coloring brightens shaded beds and weaves beautifully among hostas and other woodland plants. Easy, refined, and deer-resistant, it's a must-have for shade borders in Edina, Plymouth, and Eagan.

Landscape Uses in Minnesota
Front-of-shade-border color: Its compact size and metallic color make it ideal for edging shaded beds and walks. Space 18 inches apart.
Woodland weaving: Threads beautifully among hostas, heuchera, and green ferns. Pair with Ghost fern, hostas, and astilbe.
Best Time to Plant in Minnesota
Plant in spring (late April–May) or early fall (late August–mid September) into moist, shaded soil. Keep moist through establishment.
How to Plant Japanese Painted Fern
Dig a hole twice the root ball width at the same depth, mixing in compost. Set the crown level, backfill, water well, and mulch with shredded leaves. Space 18 inches apart.
Watering Japanese Painted Fern
First year: Keep the soil evenly moist — water every 1–2 days in dry weather.
After year one: Maintain steady moisture for the best color. Mulch to retain it; fronds may fade in dry soil.
Q: How much sun can it take?
It colors best in part to full shade. A little morning sun is fine, but hot afternoon sun fades and scorches the fronds.
Q: Does it spread?
It forms a slowly expanding clump rather than running — well-behaved and easy to place.
Q: Is it deer-resistant?
Yes — deer and rabbits rarely browse ferns.
Q: Will it survive a Minnesota winter?
Yes — hardy to zone 4, returning each spring.
