Artillery ferns ( Pilea microphylla) are not actually ferns at all but are members of the Pilea family. They are called artillery ferns because they shoot seeds with a popping sound—and sometimes for quite a distance. Despite that explosive trait, these plants are delicate and have a lovely, interesting texture. Artillery ferns are easy to grow, and they will best thrive with minimal care in a closed terrarium, as this plant loves moisture and humidity.
