When does the Epiphyllum oxypetalum bloom? A detailed explanation of its flowering period
When does the Epiphyllum oxypetalum bloom? The Epiphyllum oxypetalum generally blooms from June to August each year. In the hot summer, when the sunset glow ushers away the beautiful dusk and the clear breeze welcomes the cool night, the beautiful Epiphyllum oxypetalum blossoms. A well-grown Epiphyllum oxypetalum can bloom more than 20 flowers at the same time. When the flowers open, the room is filled with fragrance that refreshes the heart. White flowers and green stems set each other off, extremely beautiful for a time. Unfortunately, the good times do not last long; from first blooming to withering, it is only a little over 3 hours. The Epiphyllum oxypetalum has long been known as the “fairy flower”; this is probably because its rare “brief blooming” is like a fairy descending to the mortal world!
Why does the Epiphyllum oxypetalum bloom only after 21:00? It turns out that this also has a certain relationship with meteorological conditions. The petals of the Epiphyllum oxypetalum are large and delicate, and certain temperature and humidity conditions are needed for them to open. During the day the temperature is too high and the air is dry; late at night, the temperature is too low, both of which are unfavorable for the opening of the Epiphyllum oxypetalum. Only around 21:00 to 22:00, when the weather is suitably cool and warm, with the temperature at around 20 to 26°C, and the air is moist, with relative humidity above 80%, is it most suitable for the Epiphyllum oxypetalum to open. Moreover, the Epiphyllum oxypetalum is very sensitive to changes in light intensity; as night gradually falls, it senses the message that darkness is about to arrive. In this way, the buds about to open are prepared to bloom, and at nightfall, they bloom, and only bloom for a little over 3 hours. Around midnight, the temperature gradually decreases, so the Epiphyllum oxypetalum begins to wither; in this way, the blooming period of the Epiphyllum oxypetalum avoids damage from high and low temperatures.
