Tree — part of London's Tower Hamlets (6)

I believe the answer is:

poplar

(Other definitions for poplar that I've seen before include "Tree of willow family" , "Tree - London district" , "Tall tree of north temperate regions" , "Deciduous tree" , "part of London" .)

I've seen this clue in The Guardian.
