Athyrium Godzilla

Giant Japanese Fern

Like Athyrium n.'Pictum' on steroids, this giant painted fern was discovered at Plant Delights Nursery in the mid-90s and is thought to be a sporeling of 'Pictum' and the Lady Fern.
It forms a massive, arching clump of silvery fronds with green highlights and dark purple stems. Like the Lady Fern, 'Godzilla' spreads slowly where it is happiest in moist, loamy soils. Grow this fern as a low maintenance filler in shady borders combined with large hostas and Aralia 'Sun King'.

Growing and Maintenance Tips

Athyrium grows best in moist soil with a neutral to moderately acidic pH. Partial to full shade is best. To protect the crowns and tender shoots in the spring, it is best to leave the old fronds on the plant over the winter. They can be removed in the spring when the new fronds reach 15 cm (6 inches) tall. If division is necessary, do so in the spring.
