Godzilla is a giant among painted ferns, forming a huge, arching clump of silvery fronds with green highlights on dark purple stems. It reaches about 3 feet tall and can spread 4 to 6 feet wide over time.
It spreads slowly where the soil is moist and loamy, making it a low-maintenance filler for large shady borders. It combines well with big hostas and other bold shade plants.
What it looks like
Very large, arching fronds up to about 3 feet long are cut into many leaflets that are silvery gray with green shading along the centers. Stems and midribs are dark purple, showing clearly through the silver. The fronds arch outward to form a broad, mounded clump about 36 inches tall and 4 to 6 feet wide. In midsummer the plant is a full, cascading mass of silver and green, much larger than a typical painted fern.
Growing it with lavender
Godzilla needs moist shade, so plant it in a large woodland bed or under trees with hostas rather than with lavender in the sun.
Care
Grow in part to full shade in moist, loamy, humus-rich soil and water during dry spells. Hardy in zones 3 to 8. Give it plenty of room and cut away old fronds in early spring.
