In the Technical University’s Botanical Garden (founded 1840), scientists carry out botanical research. It also serves as an outdoor laboratory for experi-mental plant research. There are around 4,000 different kinds of plants to see, some of which are rare and endangered species.
A special highlight can be found in the new greenhouse: the giant water lily Victoria Cruziana. This tropical rarity with its huge, resilient floating leaves blooms for only two nights in August; first white, then pink. Every year at the time of this sensational event, the garden remains open during the evening hours.
