Stock Photo - 31 May 2021, Saxony, Leipzig: In the historic Victoria House in the University Botanical Garden, gardeners Anika Behr (r) and Janet Klingner (l) plant the still small Victoria amazonica in the 26 degree water. The leaves of the queen of the water lilies, which is actually native to South American waters, are expected to reach a diameter of up to two metres in the next few months. Built in 1876, the octagonal greenhouse is the only remaining original of the original dozen greenhouses of this type in Germany. The Botanical Garden is one of the oldest in the world.
