This fern thrives in part to full shade where moisture and humidity are plentiful and the soil is compost-rich and woodsy.

Hardy in USDA Zones 3 to 8, Japanese painted fern grows about 18 inches tall and makes a clump more than two feet wide.

To keep the soil rich and fertile, mulch planting bed with 2 or 3 inches of compost or leaf mould each spring or fall. The fronds show their best color in light shade. The plant will tolerate a small amount of morning sun in southern gardens; in northern gardens it can take more morning sun without leaf scorch.
