Ferns were popular in the Victorian era and garnered the name Pteridomania, which included gathering ferns or utilizing them in pottery/textiles. Slavic traditions incorporated this plant as anyone who views this rare flower as rich and happy for life. Finnish people say those who hold a fern seed on a midsummer night can move invisibly to find treasure.
In the United States, they ward off evil spirits when thrown into burning coals.
Today, ferns purify the air, remove formaldehyde/xylene, and improve sleep quality. They may help relieve headaches as well. An indoor fern is a versatile plant that can grow in both very small and large spaces.
