Summary

Actiniopteris radiata, commonly known as ray fern, is a small, evergreen fern native to arid and semi-arid regions, including rocky areas and scrublands across Africa, Madagascar, the Arabian Peninsula, Iran, Afghanistan, Nepal, India, Sri Lanka, Burma, and Australia. It is adapted to grow in hot, dry habitats, often at the base of rocks or in crevices, where it can withstand high temperatures and low rainfall. This fern typically forms a compact rosette of radiating fronds that resemble the spokes of a wheel, each frond reaching up to 15 cm in length.

Ray fern is valued for its unique appearance and its ability to thrive in challenging environments, making it a suitable choice for rock gardens, xeriscaping, and as an accent plant in arid landscape designs. It requires minimal care, thriving in well-drained soil and tolerating full sun to partial shade. Gardeners should consult local regulations before planting Actiniopteris radiata outside its native range.CC BY-SA 4.0
