For the pB³ exhibition, flower portraits in the form of historical black-and-white photographs were taken from the archive. The identification of the individual flowers and plants proved to be not so easy.
Now the knowledge of the visitors of the Flower Power Festival is in demand. For this purpose, there is an online flower quiz with twelve flower pictures to identify. Each of the flowers searched for can be viewed online and the plant name entered directly next to the picture.
As a small incentive in addition to the fun of puzzling, guessing and participating, there are prizes as a reward such as flower posters, books and calendars. These will be raffled off among all participants in the flower puzzle.
