Tagette flower which glows under UV light by Swen van de Vlierd

Tagetes, often known as marigolds in the Netherlands, are flowers that naturally display a fascinating characteristic when exposed to ultraviolet (UV) light. In this photo, we see a Tagetes flower that lights up spectacularly under UV radiation. The petals display vibrant fluorescent hues ranging from intense yellow to deep orange, highlighting the flower's natural patterns and textures in a mesmerising way.

Under UV light, details emerge that normally remain invisible to the naked eye. Tagetes' fluorescent properties are the result of certain pigments in the petals absorbing UV light and then re-emitting it into the visible spectrum. This creates a stunning visual effect that resembles natural neon lighting. The nuances of the colours and the brilliant patterns that become visible offer a glimpse into a hidden world that is otherwise hidden from us.

The phenomenon of UV fluorescent flowers is not only a visual spectacle, but also has a functional role in nature. Many pollinators, such as bees, have the ability to see UV light, making the flowers even more attractive to them. The brightening parts of the flower act as a kind of runway, guiding insects to the nectar and pollen. This increases the chances of pollination and thus reproduction of the plant.
