Selaginella willdenowii

Species description

Care, breeding and tankmates

Plant profile

Placement

Midground

Place Selaginella willdenowii in the midground or background of the aquarium. It needs enough space to avoid shading neighboring species. Proper placement ensures steady light exposure and water flow.

Botanical form

Stem

Selaginella willdenowii features a distinct structural form with well-defined leaves. Its stem and root structures anchor firmly into the substrate. The overall appearance provides excellent visual texture underwater.

Growth

Medium

The growth rate of Selaginella willdenowii is generally moderate under optimal conditions. Adding CO2 injection will significantly accelerate its development. However, it can adapt to slower growth in low-tech setups.

Substrate

Medium

*Selaginella willdenowii*, a striking fern-like plant often used in terrariums or paludariums, benefits from a well-draining, moderately fertile substrate. It relies on a fine, shallow root system that absorbs moisture and nutrients efficiently from light, airy soils like peat or sphagnum-based mixes. The substrate should be kept consistently moist but never completely waterlogged to prevent root suffocation. A depth of 3-5 cm is typically sufficient for its roots to anchor and support its distinctive, iridescent fronds.

Column fertilization

Recommended

Liquid fertilization is very beneficial for Selaginella willdenowii. It absorbs dissolved minerals directly from the water column. Dosing a complete micronutrient fertilizer twice a week is recommended.

Root fertilization

None

A nutrient-rich substrate strongly supports the root system of Selaginella willdenowii. Adding root tabs near its base provides essential macronutrients. This promotes a stronger base and healthier overall growth.

Trimming

Occasional

Regular trimming keeps Selaginella willdenowii looking neat and prevents overgrowth. Cut the stems just above a node to encourage branching. Remove any decaying or yellowing leaves to maintain water quality.

Propagation

spores

Propagation of Selaginella willdenowii is straightforward by taking stem cuttings. Replant the healthy cut portions directly into the substrate. They will develop new roots within a week or two.

Sensitivity

Moderate

Selaginella willdenowii is somewhat sensitive to sudden fluctuations in water parameters. It prefers stable temperatures and consistent CO2 levels. Algae can grow on its leaves if lighting is too intense.

Layout role

paludarium, Midground, group

Selaginella willdenowii plays a crucial role in creating depth in an aquascape. Its unique texture contrasts beautifully with fine-leaved plants. It works well as a focal point or a transition plant.
