The Flora und Botanischer Garten Köln (11.5 hectares) is a municipal formal park and botanical garden located adjacent to Cologne Zoological Garden at Amsterdamer Straße 34, Cologne, North Rhine-Westphalia, Germany.
The garden dates to 1863 when a private company was organized to create Flora park (5.5 hectares) as a replacement for the city's older botanical garden near the Cologne Cathedral, which in 1857 was destroyed for construction of the central railway station.
This new park was designed by Peter Joseph Lenné in 1864 in a mixed German style, incorporating French Baroque, Italian Renaissance, and English landscape garden elements.
These two gardens were united in 1920, with new glasshouses and exhibition houses for exotic and tropical plants added in the 1950s.
It also contains a number of notable trees, some dating to the garden's establishment; more than 60 specimens have been designated natural monuments.
