Elaphoglossum crinitum, commonly known as the elephant ear fern, is an epiphytic fern known for its distinctive, hairy fronds. Its leathery leaves can grow up to 30 centimetres long and are covered with dark, hair-like scales, giving the plant a unique textured appearance. 

This fern thrives in warm, humid environments and is well-suited for terrarium culture due to its preference for consistently high humidity. Its slow-growing nature and compact habit make it manageable for indoor cultivation when given the right conditions.

Native to
Elaphoglossum crinitum is native to the humid tropical forests of Central and South America, particularly from Mexico to Honduras. It typically grows as an epiphyte, attaching to trees in the shaded understory of rainforests where moisture is abundant.

Water
Keep the soil consistently moist but not waterlogged. Water the plant when the top inch of the soil feels slightly dry, ensuring excess water can drain. Avoid letting the plant sit in standing water to prevent root rot. During winter, reduce watering slightly as its growth slows.

Light
Bright, indirect light is best for Elaphoglossum crinitum. Avoid direct sunlight, which can scorch its fronds. An east- or north-facing window with filtered light is ideal. Insufficient light may lead to slower growth and less vibrant foliage.

Humidity
High humidity levels of 60-70% or more are essential. Use a humidifier or place the plant on a tray of damp pebbles to maintain appropriate moisture levels. Avoid misting the fronds directly, as this can cause fungal issues. Its preference for high humidity makes it ideal for terrarium cultivation.

Temperature
Elaphoglossum crinitum thrives in temperatures between 18-25°C (64-77°F). Keep it away from cold drafts and avoid placing it near heating or cooling vents, as sudden temperature changes can cause stress. Ensure temperatures remain above 13°C (55°F) to prevent damage.
