Java Fern grown out into a mat and secured to a backing, giving an instant head start on covering hardscape compared to attaching individual rhizomes. This listing is the large size. Skill Level Easy CO2 Not Required Requires Aqua Soil Not required — epiphyte, attach to hardscape rather than planting Type Rhizome (Epiphyte) Max Height 5-8" (large mat) Placement Midground to background, on hardscape Light Level Low (approx. 20-40 PAR) Origin Indonesia Other Also available in a smaller size (see Java Fern Mat — Small). Every mat is unique — height and shape will vary naturally. Care & Planting: Weigh or pin the mat directly onto hardscape; the rhizome will anchor itself over time and the mat backing can be trimmed away once established. Do not bury the rhizome.
