Fern 'Green Flame' (Microsorum punctatum 'Green Flame') is a tropical fern in the Polypodiaceae family, native to Southeast Asia and the Pacific Islands. It grows naturally on forest floors and rocky outcrops in humid, shaded environments.
The fronds are long, strap-shaped, and heavily ruffled along the edges, with a wavy, crinkled texture that runs the full length of each leaf. They emerge bright yellow-green and deepen to a darker green as they mature. Green Flame Fern grows in a low, spreading clump, with fronds arching outward from a central rhizome that creeps along the soil surface.
Ferns in this genus do not produce flowers. Green Flame Fern reproduces through spores, which form in raised brown clusters called sori on the undersides of mature fronds. It is a pet-friendly plant and safe for cats and dogs. It also purifies indoor air and naturally humidifies the air around it.
Place it near a kitchen or bathroom where ambient moisture stays consistently higher. Green Flame Fern is sensitive to being moved once settled, so pick a permanent spot before bringing it home. You can move it outside for summer, but place it somewhere sheltered and cover it from heavy rain. It is also sensitive to air from air conditioning vents and heaters, so keep it away from direct airflow. Under office LED lighting, it continues to grow steadily as long as the light runs for most of the day.

Green Flame Fern does best in a well-draining, peat-based or coco coir mix with added perlite.
It prefers temperatures between 60°F and 80°F and struggles below 50°F.

Q: Is Fern 'Green Flame' safe for cats and dogs?
A: Yes, it is non-toxic and pet-friendly for both cats and dogs.
Q: How do I know when it needs water?
A: Fern 'Green Flame' wilts slightly when the soil has been dry too long. Check the top inch of soil before watering rather than following a fixed schedule.
Q: Where is the best spot for Green Flame Fern indoors?
A: A north- or east-facing window works well. Keep it a few feet back from a south-facing window, as direct sun scorches the fronds.
Q: How often should I rotate it?
A: Green Flame Fern benefits from a quarter-turn every one to two weeks so all sides of the plant receive even light exposure.
Q: Can Green Flame Fern go outside in summer?
A: Yes, move it outside once temperatures stay reliably above 60°F. Choose a shaded or semi-shaded spot and shelter it from heavy rain.
Q: Why are the frond tips turning brown?
A: Brown tips on Green Flame Fern usually point to low humidity or dry air from a nearby vent. Moving it away from air conditioning or heating airflow and raising the surrounding humidity typically stops further browning.
