Planten un Blomen (German pronunciation: [ˈplantn̩ ʊn ˈbloːmn̩]) is an urban park with a size of 47 hectares (116.1 acres) in the inner-city of Hamburg, Germany.

[2] After the destruction of Hamburg's old city fortifications in the early 1800s, a green belt was established in their place; part of this makes up the modern Planten un Blomen.

[5] The modern park was established in 1933; in accordance with Nazi ideology, only German plants were included at the time.

[6] In 1953 and 1973 the Internationale Gartenbauausstellung (International Horticulture Show, IGA) were held at the park.

[5] The park has water-light concerts, public theater and music performances.
