Mirabilis Jalapa 

 The four o'clock flower-Mirabilis jalapa, this popular garden plant is starting to bloom in July.
The flowers open in the afternoon, that's where the name comes from. They stay open during the night, being pollinated by nocturnal pollinators, like the sphinx moths or hawk moths. Also called the Marvel of Peru, the flowers of this plant are splashed with different colours, like these yellow flowers with pink- magenta spots. More interesting is that as the plant matures, it can display flowers of different colors on the same plant; the yellow flowers can change to pink or white ones change to light violet.

Caring for Mirabilis plants

Once growing it is best to water beauty of the night regularly; it is also necessary to fertilise Mirabilis once a month. Once the flowering period has finished cut the plants back to ground level. If you require more Mirabilis plants then the tubers can be divided in the spring. Four o'clock plants are shrubby perennials in warm climates, growing from tuberous roots. In colder climate the foliage dies back to the ground in autumn but the tubers must be stored indoors during winter and replanted in the garden in spring.
