Boston Fern

You’ll find Boston Ferns in the wild in humid, shady areas, like swamps and forests, in South and Central America, the West Indies and Africa. They love anywhere wet, hot and not too bright. As a houseplant, they really became popular with the Victorians - those guys absolutely loved an exotic houseplant - thriving in the poorly lit, likely damp homes of the 1800s. 
When looking after one at home, the rule is to never let a Boston fern dry out. Make sure to keep the soil moist and humidity level high. Although it's very tempting, try to resist touching their fronds as they really don't like it and it might turn them brown.
