Nephrolepis Boston Ferns are an evergreen, extremely popular houseplant which has many standout features. The Boston is the perfect indoor plant which is easy to feed, water and maintain throughout the year. Its ultimate height and spread will reach up to 0.5-1m over the course of 5 years. It requires pruning when dead fronds show and situating the fern within a pot in partial shade is the recommended way to go.
