Eucalyptus Populnea, a medium sized tree that is endemic to Eastern Australia, which is commonly known as Poplar Box or Bimble Box. This tree typically, grows to a height of 20 m (66 ft).

Poplar Box is widespread in New South Wales where it is found on the western plains north from Narrandera and Pooncarie, extending into Queensland as far as Rockhampton.

It is most abundant in the northern and central sections on the western plains, becoming gradually less common in the New South Wales far west, where it is restricted to areas that are more reliably watered and sandier.

This tree can be propagated easily and is not difficult to establish. It is considered as not being an easy wood to work with; however, the outcome on a successful piece from the lathe once shaped and polished is remarkable.

The common name Bimble Box are from the Wiradjuri name for the species. Wiradjuri are the group of Aboriginal Australian people from central New South Wales.

Protected areas in which significant populations can be found include the Yathong Nature Reserve in New South Wales.
