When will the latest epiphyllum blossom?

When does epiphyllum blossom? Epiphyllum generally blossoms from June to August every year. In the hot summer, when the sunset sends away the beautiful dusk and the breeze ushered in a cool night, the beautiful epiphyllum blossoms and the well-growing epiphyllum can blossom more than 20 at the same time. When the flowers bloom, the room is fragrant and refreshing. White flowers and green stems, set off against each other, are extremely beautiful for a while. Unfortunately, the good times did not last long, from the beginning to withering, only more than 3 hours. Epiphyllum, known as "fairy flower", this is probably a rare "flash in the pan", like a fairy down to earth!

Why do epiphyllum blossom only after 21:00? It turns out that this has something to do with meteorological conditions. The petals of epiphyllum are large and delicate and need certain temperature and humidity conditions before they can open. The temperature is too high during the day, the air is dry; late at night, the temperature is too low, which is disadvantageous to the opening of epiphyllum. The weather is suitable for blooming epiphyllum when the temperature is about 20: 26 ℃, coupled with humid air and relative humidity above 80%. And epiphyllum is very sensitive to changes in light intensity, when night gradually falls, it senses the message that darkness is coming. In this way, the bud to be released is ready to blossom at night, that is, to blossom, and it will only bloom for more than 3 hours. By midnight, the temperature gradually dropped, so epiphyllum began to shrink, so the blooming period of epiphyllum avoids the injury of high temperature and low temperature.
