Scientists at the Botanic Garden have been working with scientific partner institutions all over the world to create World Flora Online, the digital image of the plants of the Earth. With the dynamic database, scientists are making all 350,000 known land plant species in the world available online for the first time. In the gardens themselves visitors can go from the Alps to Asia to America in half an hour: a distance of 23 kilometers takes them through the whole world of botany.
