Pelazoneuron ovatum, synonym Thelypteris ovata, commonly known as Ovate Marsh Fern or Ovate Maiden Fern, is a perennial fern native to wetland margins, swamps, and moist forests in the southeastern United States, particularly in Georgia’s Coastal Plain, as well as extending into the Carolinas and Florida. It typically grows up to 1.8 feet tall and features broadly ovate, pinnatifid fronds that are medium green in color. The fern prefers shaded to partly shaded conditions and is often found in the understory of forests, where it contributes to the local ecology by providing habitat for various invertebrates and serving as a food source for some wildlife species.

Ovate Marsh Fern is valued for its lush, green foliage and its ability to thrive in wet, shady garden spots where other plants might struggle. It is commonly used in shaded garden beds, woodland gardens, and naturalized areas. This fern is relatively low maintenance, requiring consistently moist soil and protection from strong winds. It is not known for significant pest or disease problems, but it can be sensitive to drought and excessive sunlight. In cultivation, it is important to mimic its natural moist, shaded habitat to ensure its success.CC BY-SA 4.0
