Species description

While the parent species, Microsorum pteropus, originates from Southeast Asia, growing epiphytically on wood and rocks along waterways, the 'Crisped Leaves' variety is a horticultural cultivar developed through selective breeding. Nevertheless, it thrives in conditions that mimic its ancestral habitat, preferring slow-moving, nutrient-rich water. Its epiphytic nature makes it perfectly suited for attachment to hardscapes rather than being buried in the substrate. Microsorum pteropus 'Crisped Leaves' belongs to the Polypodiaceae family, a large group of ferns known for their resilience and adaptability. This specific cultivar stands out due to a genetic mutation that causes the curling and undulation of the leaf margins, giving it a distinctive appearance.

Care, breeding and tankmates

This fern is remarkably tolerant of a wide range of water parameters, making it suitable for many community aquariums. It prefers temperatures between 20 and 28 C, with a slightly acidic to neutral pH (6.0-7.5) and carbonate hardness (KH) between 2 and 12. Stability of parameters is more important than specific values, and extreme fluctuations should be avoided to maintain plant health. Microsorum are generally resilient but can suffer from "Java Fern Disease" or melting, characterized by leaves becoming translucent and disintegrating, often linked to stress or poor water conditions. Another risk is excessive algae growth on leaves under conditions of too intense light or nutrient imbalances.

Geographic Origin and Distribution

This species originates from: South-East Asia (cultivar).

Plant profile

Placement
Midground

It should be attached to driftwood or rocks, ensuring the rhizome is exposed. Burying the rhizome will lead to rot. It is ideal for midground placement where its unique texture can be appreciated.

Botanical form
Rhizome, Epiphyte

It is distinguished by its beautifully rippled or 'crisped' leaf edges. The leaves are tough and leathery, growing from a thick, sturdy rhizome. Dark anchoring roots help it grip onto various hardscape materials.

Growth
Medium

It exhibits a slow growth rate typical of the Microsorum genus. Adding CO2 and moderate lighting can marginally speed up its development. It is a very low-maintenance plant that requires infrequent pruning.

Substrate
None
Column fertilization
Recommended

A basic all-in-one liquid fertilizer is usually sufficient for its needs. It is particularly sensitive to potassium deficiencies, which cause holes in the leaves. Consistent water column dosing keeps the foliage vibrant.

Root fertilization
None

Root tabs or nutrient-rich substrates are not needed for this epiphyte. The roots are adapted for clinging to surfaces rather than nutrient uptake. It derives all its sustenance from the surrounding water.

Trimming
Occasional

Maintenance is simple and involves removing dead or declining leaves at the base. Avoid cutting the leaves themselves, as they will not regrow from the cut. Removing older leaves stimulates the production of new growth.

Propagation
Division

It readily produces adventitious plantlets on the tips and edges of older leaves. Once these plantlets form roots, they can be removed and attached to new locations. Dividing the rhizome is another effective propagation method.

Sensitivity
Moderate

It is very adaptable and hardy, handling various water conditions with ease. In strongly lit aquariums, its slow-growing leaves can become a magnet for algae. Ensure good flow to keep detritus from settling on the textured leaves.

Layout role
Epiphyte, Midground

It adds incredible texture and detail to the midground of an aquascape. The wavy leaves break up the monotony of straight-edged plants. It is highly valued for creating a wild, natural look on wood and stone.
