The rare Blue Oil Fern is grown for its unusual coloring and iridescent blue sheen that gives it a glossy appearance. This epiphytic fern from Southeast Asia comes from shaded jungles in limestone regions, where the blue serves as an adaptation to capture more light in the understory. In other words, under low light the fern gets bluer. Like many ferns, keep evenly moist and grow in partial sun to shade. With attention to watering and high humidity, this Blue Oil Fern will grace your shady windowsill for years to come.
