Heart Fern, is a small, tropical fern with distinctive, heart-shaped leaves. The leaves are leathery, deep green, and have a glossy surface, giving them a striking appearance. They grow on thin, wiry, dark-colored stems, which contrast beautifully against the foliage. The undersides of the leaves often have a spore-bearing surface, a characteristic feature of ferns. This fern has a compact, clumping growth habit and is often found growing in moist, shaded environments, such as the forest floor or along rocky crevices.
- Size: Mature Height: 15–30 cm (6–12 inches). Spread: 15–25 cm (6–10 inches). Growth Rate: Slow to moderate
- Light: Prefers bright, indirect light; avoid direct sunlight, which can scorch the leaves. Tolerates low light conditions but grows best with filtered light.
- Water: Keep soil consistently moist but not waterlogged. Use room-temperature, non-chlorinated water to prevent leaf damage.
- Humidity: Requires high humidity (above 60%). Ideal for terrariums or humid environments. Use a pebble tray or humidifier if grown indoors.
- Soil: Well-draining, rich, and slightly acidic soil (such as a peat-based or orchid mix).
- Temperature: Thrives in warm temperatures (18–26°C or 65–80°F). Avoid cold drafts and temperatures below 15°C (59°F).
- Fertilization: Apply a diluted, balanced liquid fertilizer once a month during the growing season (spring and summer).
- Propagation: Can be propagated by division, but growth is slow and requires patience.
- Pests & Issues: Prone to spider mites and fungal issues if humidity or airflow is inadequate. Avoid overwatering to prevent root rot.
