Summary

Nephrolepis exaltata, commonly known as Sword Fern or Boston Fern, is an evergreen fern native to humid forests and swampy areas in the Neotropics, Florida, and the Caribbean. It typically grows to 40–90 centimeters (16–35 inches) in cultivation but can exceed 2 meters (6 feet 5 inches) in its natural habitat. The fronds are long and arching, measuring 50–250 centimeters (20–98 inches) in length and 6–15 centimeters (2.4–5.9 inches) in width, with a distinctive sword-like shape. Sword Ferns are popular for their lush, feathery foliage and are often used in hanging baskets or as ground cover in shaded gardens.

Sword Ferns are valued for their air-purifying qualities and low maintenance requirements, making them ideal houseplants. They are hardy in USDA plant hardiness zones 9-11 and can survive brief periods of frost by going dormant and resurging in spring. In cultivation, they prefer damp, nutrient-rich soil and high humidity, necessitating misting when grown indoors. While they thrive in partial to full shade outdoors, they require bright, filtered light indoors. Care should be taken in some regions as Nephrolepis exaltata can be invasive outside its native range.CC BY-SA 4.0
