It’s a kind of cactus, and if we take a look at its leaves, it is relative to the dragon fruit. No one could predict when its flower will bloom, and it only blooms in the middle of night at a short time. Javanese people believes, who could see when the flower fully bloomed, he/she would get some gift.
Wijaya Kusuma should be placed in dry and cool place (but not in fridge) and full of care. My mother had known it. When she looked after this plant, the flower would bud. But when she ignored it, it meant no flower. She told me that if we have already own this plant, we should care of it, or this magic plant could give us a big trouble if we let it die.
