Mirabilis jalapa (the four o’clock flower or marvel of Peru) is the most commonly grown ornamental species of Mirabilis, and is available in a range of colours. Mirabilis in Latin means wonderful. A curious aspect of this plant is that flowers with different colors can be found simultaneously on the same plant. Additionally, an individual flower can be splashed with different colors. Flower patterns are referred to as sectors. A single flower can be plain yellow, pink or white, or have a combination of sectors, flakes and spots. Furthermore, different combinations of flowers and patterns can occur on different flowers of the same plant. Another interesting point is a color-changing phenomenon. For example, in the yellow variety, as the plant matures, it can display flowers that gradually change to a dark pink color. Similarly white flowers can change to light violet. The flowers usually open from late afternoon onwards, hence the first of its common names. Flowers then produce a strong, sweet-smelling fragrance throughout the night, then close for good in the morning. New flowers open the following day.
