Summary

Coryphopteris simulata, commonly known as Bog Fern or Massachusetts Fern, is a deciduous fern native to moist, shaded forest floors and swampy areas in the Northeastern United States. It typically grows to a length of 61 cm (24 in) with a long and slender stalk measuring about 20.3 cm (8 in). The bright green fronds exhibit some variation in shape, contributing to the plant’s delicate texture. During the summer, it produces spores, and in winter, the leaves die back, reflecting its deciduous nature.

The Bog Fern is valued for its lush greenery and ability to thrive in shady, wet conditions, making it an ideal choice for water gardens, rain gardens, and woodland gardens. It is also used to create a naturalized setting or as a ground cover in areas with consistent moisture. Gardeners should provide full shade and ensure the soil remains consistently moist with medium drainage. While it is relatively low maintenance, it can be sensitive to drought and excessive sun.CC BY-SA 4.0
