About the Boston Fern

The Boston Fern (Nephrolepis exaltata 'Bostoniensis') is a cultivar that first appeared in a shipment of sword ferns sent to Boston in 1894. Native to tropical forests, swamps, and humid environments across the Americas and Africa, it features long, arching fronds with delicate, finely divided pinnae that create a lush, feathery cascade. A single mature plant can produce fronds over 90 cm long and spread over a meter wide. It excels as a hanging basket specimen and is recognized as one of the best natural air humidifiers and formaldehyde removers among houseplants.

Origin: Tropical regions

Care Tips

Provide bright indirect light; avoid direct sun which scorches the fronds. Keep soil consistently moist but not waterlogged -- Boston Ferns are sensitive to drought and will shed leaflets if allowed to dry out. High humidity (above 50%) is essential; mist daily, use a pebble tray, or place in a naturally humid room like a bathroom. Brown, crispy frond tips signal insufficient humidity. Feed with a diluted liquid fertilizer every 2-4 weeks during the growing season. Remove dead fronds at the base. Watch for scale and mealybugs. Propagate by dividing the root ball in spring.
