Microsorum pteropus ‘Broad Leaf’ Java Fern - Immersed Potted Plant

Microsorum pteropus ‘Broad Leaf’, widely known as ‘Broad Leaf’ Java Fern, is a robust and visually striking variant of the classic Java Fern. Its wider, longer leaves create a bold, flowing look that adds instant impact to aquascapes. Like all Java Ferns, this plant is incredibly hardy, making it a favourite among both beginners and seasoned aquascapers. It thrives when attached to hardscape and offers natural shelter for fish and shrimp.

Physical Characteristics:

• Leaf Shape & Size: Elongated, strap-like leaves with a broader width compared to the standard Java Fern; individual leaves can grow up to 30–40 cm in length in optimal conditions.

• Colour: Rich green with a semi-glossy finish. New growth emerges lighter and darkens as it matures.

• Growth Habit: Slow to moderate growth, forming dense clusters of arching foliage from a central rhizome.

Aquarium Requirements:

• Lighting: Low to medium. High light is tolerated but not necessary and should be balanced to avoid algae on leaves.

• CO₂: Not required. Grows well in low-tech setups.

• Temperature: 20–28 °C

• pH Range: 6.0–7.5

• Water Hardness: Soft to moderately hard

• Substrate: Does not need to be planted in substrate. Best when attached to rocks, wood, or decor using thread or glue. Avoid burying the rhizome, as it will rot.

Planting Instructions:
Attach the plant’s rhizome to hardscape using fishing line, cotton thread, or aquarium-safe glue. Over time, it will anchor itself with fine roots. Avoid burying any part of the rhizome in the substrate.

Care & Maintenance:

• Easy to care for and forgiving of varied conditions.

• Remove old or algae-covered leaves by trimming at the rhizome.

• Fertilisation is optional but trace elements can support healthy growth.

• Can occasionally develop black spots (spore dots) which are natural and not a sign of disease.

Propagation:
Reproduces through adventitious plantlets that form on mature leaves. Once plantlets develop several leaves and roots, they can be gently removed and attached elsewhere in the aquarium.

Aquascaping Use:
Perfect for backgrounds or as a centrepiece on driftwood or rock in medium to large tanks. The broad leaves offer a lush, wild appearance that pairs beautifully with mosses and finer-leaved plants. Its shade-tolerant nature makes it ideal for shaded corners and under overhangs.

Key Benefits:

• Undemanding and ideal for low-maintenance tanks

• Provides excellent cover for shrimp and small fish

• No need for CO₂ or intense lighting

• Doesn’t require planting in substrate

Microsorum pteropus ‘Broad Leaf’ is a stunning, low-maintenance plant that brings volume, movement, and structure to any aquascape. Whether you're building a nature-style layout or simply need a durable green anchor in your hardscape, this Java Fern variety offers timeless beauty with minimal fuss.
