Marvel of Peru is one of this flower's common names. The marvel is that the flowers on one plant vary in colour. This amazed plant collectors when it was first collected in the 1500s. The flowers can be white, red, pink or yellow, or more often that not, a combination of these colours. As well, the flowers may change colour as they age.
It has other common names including pretty by night and 4 o'clock flower. Flowers open in the late afternoon and close in the morning. The flowers are strongly scented.
This flower is closing in the morning. The style and the stamens are curling back into the flower.
