Asplenium stoloniferum (Running Spleenwort)

The term 'running' refers to the plant's tendency to spread via stolons or offsets. As it grows, it will produce small plantlets along its fronds or runners, which can root and colonize the surrounding soil or substrate.

While it is a fascinating specimen, it is best suited for hobbyists who have experience with ferns. Because it thrives in specific humidity and moisture levels, it requires a stable environment typical of a well-maintained terrarium.

As a fern, it prefers shaded or indirect light conditions. Avoid placing it in direct sunlight, which can scorch the delicate fronds and dry out the plant too quickly.

Since this species spreads by producing plantlets, you can easily manage its size by pruning back the runners. If you prefer a fuller look, you can leave the offsets attached to allow the plant to fill in the space naturally.

This fern thrives in a moisture-retentive but well-draining substrate. A mix designed for tropical terrarium plants, such as one containing coco coir, sphagnum moss, or fine bark, will help maintain the necessary humidity around the roots.
