Bowra is characterised by Mulga communities, mixed with Poplar Box and bloodwoods, on the scarp and ridges in the north of the property.
Within the Sydney region, it is found in grassland to open forest communities, associated with woodland trees such as smooth-barked apple (Angophora costata), Sydney peppermint (Eucalyptus piperita), silvertop ash (E. sieberi) and red bloodwood (Corymbia gummifera), in scrub with coastal banksia (Banksia integrifolia) and broad-leaved apple (Angophora subvelutina).
The vegetation on the Ngarrabullgan tabletop (plateau) has been described as wet sclerophyll forests, mainly of a bloodwood species of Eucalyptus, with a well-developed understory.
The Eucalypt Walk features five gardens displaying some well known eucalypt species, the Ironbark Garden, the Box Garden, the Peppermint Garden, the Bloodwood Garden, and the Stringybark Garden.
