Epiphyllum oxypetalum, commonly known as Queen of the Night, Night-blooming Cereus, or Dutchman’s Pipe Cactus, is a species of epiphytic cactus native to Central and South America. Here are some key features and care tips for Epiphyllum oxypetalum:

1. Appearance: Epiphyllum oxypetalum is characterized by its flattened, leaf-like stems that resemble long, narrow leaves. The stems are typically dark green and have serrated edges. This cactus produces large, fragrant, white flowers that bloom at night and last only one night, often with a waxy texture and a star-shaped form.
2. Growing Conditions: Epiphyllum oxypetalum thrives in bright, indirect light but can tolerate some direct sunlight, especially during the morning hours. It prefers temperatures between 60°F and 90°F (15°C to 32°C) and requires well-draining soil that allows water to flow through freely. This plant is often grown as a hanging or trailing plant in baskets or pots.
3. Watering: Keep the soil evenly moist during the growing season (spring through fall), allowing the top inch of soil to dry out between waterings. Reduce watering in winter when the plant is dormant. Epiphyllum oxypetalum is susceptible to root rot if kept too wet, so be cautious not to overwater.
