Selaginella involvens, commonly known as Spreading Clubmoss, is an evergreen perennial herb native to a variety of habitats including moist forest floors, shaded slopes, and limestone regions in parts of Asia such as China, India, Japan, Korea, the Philippines, Russia (Siberia), Taiwan, and northern Thailand. It typically grows up to 18 inches tall and is characterized by its small, scale-like leaves and creeping stems that form dense mats. The plant is not particularly showy, but its delicate, fern-like appearance adds texture to garden compositions.

Spreading Clubmoss is valued for its use in shaded rock gardens, terrariums, and as ground cover in woodland gardens due to its tolerance of low light conditions. It thrives in moist, well-drained soil with high organic content and prefers part shade to full shade environments. In herbal medicine, it is used to treat gout and hyperuricemia. While it is generally low-maintenance, it can be sensitive to overwatering and may suffer from root rot if drainage is inadequate. It is not known to be invasive or to have aggressive roots, making it a safe choice for cultivation in a variety of settings.CC BY-SA 4.0
