SCIENTIFIC NAME: Microsorum thailandicum

KNOWN AS: Blue Oil Fern, Steere's Fern

CLIMATE (LOCATION): Southeast Asia (Thailand, Vietnam, Laos) | Tropical Rainforest (Epiphyte/Lithophyte)

DESCRIPTION: The Blue Oil Fern is one of the most mesmerizing plants in the world. Its leathery, strap-like fronds possess a stunning metallic blue iridescence. This isn't a pigment, but a biological trick: the plant uses "iridoplasts" to slow down light and capture more energy in the dim rainforest understory. Under a flashlight or bright indirect light, the leaves glow with an electric, neon-blue "oil slick" sheen.
