Microsorum pteropus 'Windeløv', the Windeløv Java Fern, is a refined form of the classic Java Fern set apart by its finely divided, curly leaf tips that give each frond a lace-like, feathery finish. It is an epiphyte, so it grows attached to hardscape rather than in the substrate, and sits nicely as a midground or accent plant against driftwood and rock.This is one of the easiest plants to keep and it fits low-tech tanks well, tolerating low light and no added CO2. Anchor the rhizome to wood or stone with thread or glue and leave the rhizome itself above the surface, as burying it can cause it to rot. Growth is slow and steady, the leaves resist algae, and mature fronds produce small plantlets that you can detach and attach elsewhere to spread it through the tank. It suits community tanks, nano tanks and lush jungle-style scapes.Care at a glance Placement: Midground, attached to hardscape Lighting: Low CO2: Low, not required Growth rate: Slow Difficulty: Beginner Colour: Green Our plants are harvested fresh and algae free, and the conversion to submerged form begins in our grow-out tanks to maximise your success once it settles into your aquarium. Submerged means the plant grows fully underwater, which is how it lives long term in your tank. Emersed means it was grown with its leaves above the waterline, so some early leaves may adjust or be replaced as it settles into submerged growth.
