Poplar is a mainly residential district of the London Borough of Tower Hamlets, East London, about 5.5 miles east of Charing Cross. Poplar includes a part of the Canary Wharf, the Poplar Dock, as well as the Lansbury Estate and Chrisp Street Market. The area takes its name from the Black Poplar tree, a large and locally very rare species that once thrived in the wet conditions which the Thames and Lea formerly brought to much of the neighbourhood.
