My Epiphyllum oxypetalum:
Queen of the Night (Epiphyllum oxypetalum) bloomed three nights this week and I missed it every single time, only to notice spent blooms the next day!
Tonight I looked and no blooms on the Epiphyllum but I found two other night bloomers showing their stuff:
Ipomoea alba (Evening Glory) ............ and Cereus repandus (Apple Cactus)
