Ultraviolet photograph of a Winter jasmine (Jasminum nudiflorum) flower growing near the end of the stem, with two flower buds yet to open below it.
The flower has a dark marking around the centre visible in ultraviolet, which is not present in visible light. This is commonly known as a 'nectar guide', as it is thought that it helps guide bees and other insects (which can see ultraviolet light) to the centre of the flower where the nectar and pollen are located.
The sepals and stem appear darker in comparison to the petals in ultraviolet than they do in visible light.
Although native to China, the plant has been cultivated and is grown throughout the world. It flowers from November to March, one of the few plants that flower over the winter.
