1.Selaginella Kraussiana — Overview
Selaginella kraussiana, commonly known as African clubmoss, Krauss' spikemoss, or trailing spikemoss, is a captivating perennial herbaceous plant belonging to the ancient family Selaginellaceae, representing one of the oldest extant lineages of vascular plants, the lycophytes. This species is admired for its delicate, fern-like appearance and its remarkable ability to form dense, vibrant green mats or cushions, making it a highly valued ground cover in horticulture and a popular choice for terrariums and indoor plant collections. Morphologically, it is characterized by small, scale-like leaves, known as microphylls, which are typically lanceolate to ovate and arranged spirally along slender, creeping stems.
These stems branch profusely, creating a lush, layered texture that can spread horizontally, covering significant areas. While its mature height usually ranges from a modest 10 to 30 centimeters, its lateral spread can be much wider, forming an expansive carpet of foliage. Unlike true mosses, Selaginella possesses true vascular tissue, distinguishing it as a more evolutionarily advanced plant.
The root system is shallow and fibrous, efficiently anchoring the plant and absorbing moisture from the upper soil layers.
Geographically, Selaginella kraussiana is indigenous to tropical and subtropical regions of Southern Africa, particularly thriving in parts of South Africa, Zimbabwe, and Mozambique. Its natural habitat is typically found in shaded, moist, and often humid environments, such as forest floors, stream banks, and rocky crevices, where it flourishes under the protective canopy of larger vegetation. This preference for high humidity and consistent moisture levels is crucial to its survival and explains its adaptability to indoor cultivation in humid household environments like bathrooms.
Taxonomically, it is classified within the genus Selaginella, which is the sole surviving member and the largest genus of heterosporous lycophytes, encompassing approximately 700 to 750 species globally. Its unique morphology includes the presence of ligules at the base of its microphylls, a distinctive feature within the genus.

6.Selaginella Kraussiana — Water Requirements
- ✓ Light — Prefers low to moderate light; avoid direct, intense sunlight which can scorch its delicate foliage.
- ✓ Soil — Requires consistently moist, well-draining, humus-rich soil, ideally with a slightly acidic to neutral pH.
- ✓ Humidity — Thrives in high humidity environments; misting regularly or placing in terrariums/bathrooms is highly beneficial.
- ✓ Watering — Keep the soil consistently damp but never waterlogged; use distilled or rainwater to prevent mineral buildup.
- ✓ Temperature — Best grown in warm temperatures, typically between 18°C and 27°C (65°F-80°F); protect from cold drafts.
- ✓ Propagation — Easily propagated by stem cuttings, which root readily in moist soil or water, or by dividing established clumps.
- ✓ Fertilization — Feed sparingly with a diluted liquid fertilizer (half-strength) every 2-4 weeks during the growing season (spring/summer).
- ✓ Pruning — Minimal pruning is needed, primarily to remove any yellowing or dead foliage to maintain its neat appearance.
