Microsorum pteropus 'Undulata'

Microsorum pteropus 'Undulata' is a cultivar selected for its distinctly wavy, undulated frond margins — the fronds are broad, mid-green, and deeply crimped along their edges, creating a lively, organic appearance that is more dynamic than the smooth-margined standard Java fern. The undulation becomes more pronounced in actively growing plants under good conditions. Fronds reach 20–30 cm and are held on a typical Java fern rhizome.

This cultivar is appreciated for the unique texture its wavy fronds introduce into aquascape compositions, particularly when positioned in areas with gentle water flow where the undulating margins sway and ripple attractively. Care requirements are identical to other Java fern varieties — easy, tolerant of low light and diverse water parameters, and requiring only attachment to hardscape. It is suitable for both experienced and beginner aquascapers and pairs well with mosses, Anubias, and Bucephalandra on driftwood arrangements.
