Pre flowering state
The flower stem is hook shaped, and the top of the flower bud is upward p>
In this state, it is about to bloom. You can observe it after 9 p.m. and you can see the legendary "flash in the pan" p>
Why only bloom at night
Under normal circumstances, the flowering period of Epiphyllum is at night, while the flowering can be seen during the day is artificial. Epiphyllum comes from the desert in tropical areas. The environment in the desert is dry and the temperature is high. The long-term survival of Epiphyllum has created the attribute of heat and drought resistance. Due to the high temperature during the day, the greater the evaporation of water, and the flowers cannot bloom without sufficient water. However, at night, the temperature will also decrease, and the evaporation of water will also decrease. This is the best time for flowering p>
Optimum conditions
The reason why Epiphyllum is short is that its flowering requires high temperature. When the temperature is between 20 and 26 degrees and the air humidity is more than 80%, the humidity at night is higher and the temperature is lower than that during the day. In the early morning, the temperature is getting lower and lower, and the flowers will wither slowly. That's why it's called "instant". It's only a few hours p>
