A low-growing evergreen clubmoss with delicate, fan-like fronds that spreads slowly across moist woodland floors. Non-flowering, it reproduces via spores and is prized for its fine texture in shade gardens.

Why grow it

Fan clubmoss offers finer, more delicate texture than many ground-covering ferns in deep shade, making it useful for adding visual interest to woodland gardens where other groundcovers struggle. Unlike flowering shade plants, it requires no deadheading or seasonal cleanup, and its slow spread means it won't overwhelm adjacent plantings. It performs particularly well in acidic, consistently moist soils where many ornamental groundcovers decline.

Watch out for

This species is sensitive to disturbance and compaction, so site it in areas away from foot traffic and avoid cultivating the soil around established patches. It may take several seasons to establish and spread noticeably, so patience is required during the early growing period. Very dry conditions or prolonged drought stress can cause decline, even though establishment may take time.
