Winter hardy to USDA Zones 10-12. In St. Louis, it is easily grown indoors. Use a peaty, soil-based potting mix. Site in bright indirect light with no direct sun. Tolerant of some shade. Soils should be kept consistently moist, with only a slight reduction in watering from fall to late winter. Prefers high humidity and may appreciate being set on a tray of wet pebbles. Will shed fronds if soils dry out, at which point all fronds may be cut back to about 2” to regenerate.
Boston fern (also sword fern) is an evergreen fern that grows with an upright spreading habit to 3’ tall and as wide. It is one of the easiest of the ferns to grow indoors. Fronds initially grow upward but arch gracefully and then droop with age.
No serious insect or disease problems. Scale, mealybugs and white fly may appear.
Indoor fern, perhaps best for pedestals or hanging baskets.
