Epiphyllum oxypetalum is commonly called “Night Blooming Cereus”. At one time the botanical name was Cereus now it is an Epiphyllum. This is an old heirloom plant that has large white flowers that open at night. Each flower is open for only one night. Sometimes the growers of this plant will have a party and stay up late to watch the flowers open. It is very dramatic. It makes a large plant 2 to 4 feet across. Easy to grow. Give it bright light. It is usually moved outside in the summer and inside for the winter, to protect it from freezing.
Shade to partial sun, temp. 40 to 95 degrees, 2 to 4ft, across, allow it to get fairly dry between watering
