Oxalis Triangularis, Butterfly Plant Purple Care Guide :

Light Requirements

Oxalis triangularis prefers bright, indirect light for best leaf color. A location near an east- or north-facing window works perfectly. It can tolerate mild morning sunlight, but avoid harsh afternoon sun, as this may cause scorching or fading of the purple leaves. If the leaves look pale, leggy, or stretched, the plant is probably not receiving enough light. Rotating the pot every few days ensures even growth.

Watering

This plant enjoys consistently moist—but not soggy—soil. Water when the top 2–3 cm of soil feels dry to the touch. Overwatering is the most common problem and may lead to root rot or yellowing leaves. Ensure excess water drains out completely. In winter or during its natural dormancy phase, reduce watering significantly because the plant slows down growth. Always use room-temperature water to avoid shocking the roots.

Soil Mix

Oxalis triangularis prefers a well-draining, breathable soil mix. A good combination is:

• 50% normal garden or potting soil

• 30% cocopeat or peat moss

• 20% perlite or sand

This mixture keeps the soil airy, preventing waterlogging while retaining enough moisture for the roots.

Temperature & Humidity

Ideal temperatures range between 18°C and 28°C. The plant does not tolerate extreme heat or frost. If temperatures exceed 32°C, move the plant to a shady area and mist lightly in the morning. Oxalis thrives in average room humidity, so it doesn’t require special humidity trays. But extremely dry air may cause the leaves to crisp at the edges.

Fertilizing

Feed your Oxalis triangularis every 30–40 days during the active growing season (spring and monsoon). A mild liquid fertilizer diluted to half strength works best. Avoid heavy or chemical-rich fertilizers because this plant is sensitive to overfeeding. Too much fertilizer can distort leaf shape or reduce flowering.

Pot Selection

Choose a pot with good drainage and preferably a wide, shallow shape, as Oxalis grows from small bulbs or rhizomes spreading horizontally. Terracotta pots are ideal because they allow moisture to evaporate naturally, preventing excess wetness.

Dormancy Period

One unique aspect of the Purple Butterfly Plant is its natural dormancy phase, usually occurring once a year, often in extreme heat or during winter. During dormancy, the leaves may turn yellow, droop, or completely die back. This is normal—don’t panic!
Steps during dormancy:

• Stop or reduce watering.

• Keep the pot in a cool, dry place.

• Do not disturb the bulbs.

After 4–8 weeks, new shoots will emerge, indicating that the plant has awakened. Slowly resume normal watering and fertilizing.

Propagation

Propagation is very easy. Oxalis multiplies through bulbs or tubers. You can separate the bulbs and plant them in new pots. Plant bulbs 1–2 cm below the soil surface and water lightly until growth starts.

Common Problems

• Yellow leaves: Overwatering or natural dormancy.

• Leaves not opening: Too much heat or insufficient light.

• Pale color: Low light conditions.

• Drooping leaves: Underwatering or temporary stress.

Addressing these issues quickly will help the plant recover.

Conclusion

Oxalis triangularis is a charming, low-maintenance plant perfect for bright indoor spaces. With the right light, moderate watering, well-draining soil, and understanding of its dormancy cycle, you can enjoy healthy purple foliage and delicate blooms throughout the year. This plant rewards good care with fast growth, vibrant leaves, and easy propagation—making it ideal for beginners and collectors alike.
