Greenhouse Production of Boston Ferns
The Boston fern is actually a cultivar of a wild fern found in Florida called the Sword Fern (Nephrolepis exaltata). The sword fern has 3- to 4-foot erect fronds (fern leaf), and was popular as a house plant in the U.S. and Eu rope in the middle to late nineteenth century. 'Bostoniensis' was discovered by chance in a large shipment of Sword Ferns from a Phila delphia grower to a Boston distributor in 1894. Since then, variants have given rise to one of the largest and most popular groups of fern cultivars.
