What is Oxalis Hedysaroides?
Few houseplants can compete with the captivating beauty of Oxalis hedysaroides rubra, also known as the Fire Fern. Its mesmerizing, clover-shaped leaves transition from a vibrant green to a fiery, deep red under sufficient sunlight. This unique color play, coupled with delicate yellow blooms, has turned this tropical wonder into a prized possession for plant enthusiasts like myself, Ferb Vu.
569 Species in Genus Oxalis
Over the past year, I’ve been enthralled by my Fire Fern’s growth and quirky habits. From the way its leaves fold inwards at night like tiny hands in prayer, to its vibrant response to sunlight, it’s become a source of constant fascination. But my passion for this plant extends beyond aesthetics. Witnessing its resilience and the ease with which it propagates has fueled a desire to share its fiery charm with others.
The Fire Fern hails from the lush rainforests of Colombia and Ecuador. Unlike its namesake, it’s not a true fern, but a member of the wood sorrel family (Oxalis). This tropical lineage translates to a preference for warm, humid environments with bright, indirect sunlight. While the vibrant red foliage is the plant’s most striking feature, it also boasts delicate, trumpet-shaped yellow flowers that bloom sporadically throughout the year.
One of the Fire Fern’s most endearing qualities is its nyctinastic behavior. This fancy term simply means the leaves respond to light and darkness. During the day, they unfurl to capture sunlight, creating a mesmerizing, clover-shaped canopy. As dusk approaches, the leaves gracefully fold inwards, resembling tiny hands.
How to care for Oxalis Hedysaroides?
If you’re captivated by the Fire Fern’s fiery charm, here’s what you need to know to keep it thriving:
- Light: Oxalis hedysaroides rubra thrives in bright, indirect sunlight. Avoid harsh midday sun, as this can scorch the leaves.
- Watering: Maintain consistent moisture in the soil, but avoid waterlogging. Allow the top inch of soil to dry slightly between waterings.
- Humidity: As a native of the rainforest, the Fire Fern appreciates moderate to high humidity levels. Consider using a pebble tray or humidifier to create a more tropical environment.
- Soil: Opt for a well-draining, airy potting mix. A mixture of potting soil, perlite, and orchid bark can provide the ideal balance.
- Temperature: The Fire Fern prefers warm temperatures between 65°F and 80°F (18°C – 27°C). Avoid exposing it to sudden temperature fluctuations or drafts.
How to propagate Oxalis Hedysaroides?
One of the most rewarding aspects of caring for the Fire Fern is its ease of propagation. This allows you to share its fiery charm with friends and family, or simply expand your own indoor jungle. Here are two effective methods for propagating your Oxalis hedysaroides rubra:
- Division: During repotting, you can gently divide the plant’s bulbils (underground storage organs) to create new plants. Ensure each division has at least two or three healthy bulbs for successful propagation.
- Leaf Cuttings: Select a healthy leaf with a short petiole (leaf stalk) attached. Plant the petiole base in a pot with a well-draining mix and keep the soil moist. With proper care, new growth should emerge within a few weeks.

- Ferns: True ferns, like the Maidenhair Fern (Adiantum spp.) with their graceful fronds, create a harmonious and lush aesthetic alongside the Fire Fern.
With its captivating beauty, resilience, and ease of propagation, the Fire Fern has become a cherished member of my indoor plant collection. By following these simple care tips and exploring propagation methods, you too can cultivate a piece of the rainforest in your own home and share the fiery charm of Oxalis hedysaroides rubra with others.
