The Boston fern (Nephrolepis exaltata) is a spreading plant is often grown in hanging baskets or similar conditions. The leaflets are in a clearly alternate pattern. The fonds of the fern may be three feet long and span six inches, each pinnae being about three inches. (Pinnae are the small "leaflets" on either side of the midrib.) The pinnae are generally deltoid, as seen in the picture to the right. The pinnate vein pattern is also visible on these highly compound leaves. The edges appear slightly serrate.
Life cycle and hardiness
The Boston fern is a perennial in the USDA hardiness zones 9 through 11. Although the fern may appear totally dead due to frost, it will re-emerge in the spring. In general, the Boston Fern likes damp, but not soggy soil that is rich in nutrients. Of the comm
The first fossil records of ferns date back to the early Carboniferous era. By the Triassic period, there is the first evidence of ferns related to several modern families. During the Cretaceous, many modern families of ferns first appeared.
Classification
Ferns have traditionally been grouped in the class Filices, but some modern classifications assign them their own division in the plant kingdom, known as Pteridophyta. Variety: Bostoniensis
*This variety of fern has been clasified under the Davalliaceae, Polypodiaceae, and Oleandraceae families by various authorities.
