Description
Nephrolepis exaltata is the most popular and easiest to maintain tropical fern. It originates from subtropical to tropical America, ranging from the southern USA through Central America and the Caribbean to South Brazil. As an ornamental plant, it is widespread and has also become naturalized in many tropical regions of the world. The sword fern grows, for example, on rotting tree trunks in swamps, on rocks and slopes, often also as an epiphyte on palms. It forms extensive hanging frond bushes, the narrow, light to medium green fronds can grow about 60-90 cm long. The rootstock forms many thin runners.
There are various cultivars of this species; 'Bostoniensis' has broadly lanceolate leaves with undivided leaflets.
The Boston sword fern grows in well-drained soil, which should neither completely dry out nor be waterlogged. Once well established, it can be fed with a houseplant fertilizer. The species is a half-shade plant; a bright, but not fully sunny spot is ideal. The temperature is best above 20 °C and should not drop below 14 °C. The sword fern can be easily propagated by dividing its multi-headed rootstock, as well as through young plants at the ends of the runners.
Nephrolepis exaltata 'Bostoniensis' is a low-maintenance, lushly growing, large fern for tropical terrariums, suitable for both rainforest and drier terrarium types. Its palm-like clumps with hanging fronds look best at an elevated position, such as on back walls or on tree stumps. Even as a young plant, it forms a pretty accent on the terrarium floor.
