Botanischer Sondergarten Wandsbek, Municipal botanical garden in Wandsbek, Hamburg, Germany.

The Botanischer Sondergarten Wandsbek covers almost 2 hectares between Walddörferstraße and Am Schulgarten, of which 1.5 hectares are parkland; the rest holds buildings, greenhouses and the access road. It lies by the Wandse floodplain where the Rahlau meets the Wandse, near Fischers Park, and holds over 1,000 plant species in the park, greenhouses and plant boxes.

The garden was laid out in 1923 as a school garden by the Wandsbek teachers' association, which is recalled by the neighbouring street name Am Schulgarten. In 1953 it was renamed Botanischer Sondergarten Wandsbek. During the Second World War the grounds were used to grow vegetables to feed the population.

The garden serves as a place for direct nature experience, where visitors can explore different plant families and ecosystems up close. Regular exhibitions and programs here help people understand how plants and animals depend on each other and why nature needs protection.

The garden areas are open daily from morning until sunset and easily accessible, while the greenhouse has limited hours on certain weekdays. The location within a larger park means you can spend as much time exploring as you like without feeling rushed.

Since 2005 the garden has awarded a "Poisonous Plant of the Year": a shortlist in the categories herb, perennial and shrub/tree is presented, and visitors vote on the winner for the following year. The chosen plant is then displayed with information boards in the greenhouses throughout the year.
