The Boston Fern (Nephrolepis exaltata), also known as the Sword Fern, is a popular and classic choice for indoor and outdoor fern gardens. Here are some key features and care tips for Boston Ferns:

1. Foliage: Boston Ferns have feathery, lance-shaped fronds that arise from a central rosette. The bright green, arching fronds give the plant a lush and graceful appearance.

2. Size: Boston Ferns can vary in size, but they typically reach a height of 1 to 3 feet with a similar spread. The arching fronds can create a fuller, spreading appearance.

3. Habitat: In their native habitat, Boston Ferns are often found in moist, shaded woodlands. As indoor plants, they are well-suited for areas with indirect light and high humidity.

4. Light Requirements: Boston Ferns prefer bright, indirect light. While they can tolerate some direct sunlight, prolonged exposure may lead to frond burn. They are well-suited for areas with filtered sunlight or partial shade.

5. Watering: Boston Ferns thrive in consistently moist soil. It's essential to keep the soil evenly moist but not waterlogged. They may require more frequent watering in warm or dry conditions.

6. Humidity: These ferns appreciate high humidity levels. Indoor plants may benefit from occasional misting or placement in a humid environment, such as a bathroom.

7. Temperature: Boston Ferns prefer temperatures between 60-75°F (15-24°C). They can tolerate slightly cooler temperatures but should be protected from drafts and cold extremes.

8. Soil: Well-draining, rich, and slightly acidic soil is ideal for Boston Ferns. A mix of peat moss, perlite, and potting mix can create a suitable growing medium.

9. Fertilization: During the growing season (spring and summer), you can feed your Boston Fern with a balanced, water-soluble fertilizer every 4-6 weeks. Reduce or stop fertilizing in the fall and winter when growth slows.

10. Pruning: Remove any yellow or dead fronds regularly to promote new growth and maintain the plant's appearance.

11. Pests: Keep an eye out for common pests like spider mites and scale insects. Regularly inspect the plant and treat any pest issues promptly.

Boston Ferns are often chosen for their air-purifying qualities and aesthetic appeal. Whether grown indoors or outdoors in suitable climates, they add a touch of elegance with their lush green fronds. Indoor Boston Ferns are commonly used as hanging basket plants, while outdoor plants may be used in shaded gardens or as ground cover in suitable climates.
