Night Blooming Epiphyllum

My mother used to let us stay up to watch this plant bloom when my sister and I were young. It usually bloomed late at night and would only last one night. Mom planted her much larger plant in a dragon pot. I recently bought this plant at the local market and there was one flower which had already bloomed. I took it home to my balcony, watered daily and fertilised it. I soon noticed a large number of flower buds on several leaf margins. I missed the first bloom (see above photo) which bloomed the night before but the I managed to photograph this one. There is a delicate fragrance when it blooms. I had to bring it into the kitchen to photograph it without the flash.
