Diplazium expansum, commonly known as Broadleaf Glade Fern, is an evergreen perennial fern native to Mexico, Central and South America. It thrives in the understory of tropical rainforests, often in moist, shaded areas near streams or on forest floors with rich organic matter. This fern typically grows at a moderate rate to a height of 2-6 feet (0.6-1.8 meters) and a width of 2-4 feet (0.6-1.2 meters), featuring large, broadly lance-shaped fronds that create a lush, dense appearance.

Broadleaf Glade Fern is valued for its ability to add a tropical feel to shaded garden areas and is often used in woodland gardens, as a ground cover, or in containers for patios and indoor settings. It requires consistently moist soil and benefits from high humidity, making it suitable for a rain garden or a water feature’s edge. While it prefers part shade or full shade, it is adaptable to various soil types, including clay or loam, as long as they are well-draining. Gardeners should ensure regular watering, especially during dry periods, to maintain its vibrant green foliage.CC BY-SA 4.0
