Crocodile Fern

Microsorum musifolium is a tropical fern grown for its leathery, strap-shaped green fronds and distinctive textured surface. It naturally grows as an epiphyte, though it also adapts to pots and shaded garden settings in warm climates. ## Light and Moisture Give it bright, filtered light or partial to full shade; direct sun can scorch the fronds. Use a light, well-drained growing medium that retains some moisture, and water when the surface begins to feel dry. Warm temperatures and higher humidity suit this rainforest fern. The [North Carolina Extension Plant Toolbox](https://plants.ces.ncsu.edu/plants/microsorum-musifolium/common-name/alligator-fern/) recommends avoiding cold drafts and temperatures below 50°F. ## Size and Use As a houseplant, it commonly reaches about 1–3 feet tall and wide, with fronds up to two feet long; wild fronds can be longer. The [Chicago Botanic Garden profile](https://www.chicagobotanic.org/plant-information/plant-finder/microsorum-musifolium-crocodile-fern) notes its epiphytic habit and filtered-light preference. For taxonomy and native range, see [Kew Plants of the World Online](https://powo.science.kew.org/taxon/urn:lsid:ipni.org:names:17341220-1). ## Maintenance Remove damaged fronds at their base. Propagate by division in spring or early summer, and avoid leaving the potting medium waterlogged; good drainage helps reduce the risk of root rot.
