What is the scientific name of the Boston Fern?

The scientific name of the Boston Fern is indeed Nephrolepis exaltata 'Bostoniensis'. This species is well-known for its lush, feathery fronds and is a popular choice for both indoor and outdoor gardening. The specific epithet 'exaltata' refers to its erect and lofty growth habit, while 'Bostoniensis' indicates its specific cultivar, which is particularly associated with its cultivation in Boston, enhancing its cultural significance.

In contrast, other options listed are names of different plant species. Philodendron sp. refers to a genus of tropical plants that are mainly characterized by their large leaves and are often used in interior landscaping. Schefflera sp. denotes a genus commonly known as umbrella trees, which also have distinct foliage but are not related to ferns. Plectranthus australis, known as the Swedish Ivy, is a trailing herbaceous plant and does not share the fern characteristics. Each of these alternatives pertains to entirely different botanic families and traits, reinforcing why Nephrolepis exaltata 'Bostoniensis' is specifically identifiable as the Boston Fern.
