The species has erect fronds, but Nephrolepis exaltata 'Bostoniensis' (Boston fern), has gracefully arching fronds.
It is debated how it's name came to be. One proposal is that the mutation was discovered in a shipment of N. exaltata to Boston from Philadelphia in 1894.
Other proposals were documented by David Fairchild who stated the term came from Florida pioneer nurseryman John Soar who sent the plants to his friend in Boston.
It is common in humid forests and swamps, especially in northern South America, Mexico, Central America, Florida, the West Indies, Polynesia and Africa. It's also a very popular house plant, often grown in hanging baskets or similar conditions.
The fern thrives best in humid conditions, so when grown as a house plant it becomes necessary to mist the plant when relative humidity falls below around 80%.
