Lesueur National Park lies in the Geraldton Sandplains [[bioregions|bioregion]], which is characterised by scrubby heath with a high number of plants from the family [[Proteaceae]].

Vegetation in the park is structurally complex, with patches of woodland amongst shrublands.<ref name=CALM>{{cite web|title=Management Plan:Lesueur National Park and Coomallo Nature Reserve1995 - 2005|publisher=Department of Conservation and Land Management|year=1995|url=http://www.naturebase.net/pdf/nature/management/lesueur.pdf|access-date=6 December 2009|url-status=dead|archive-url=https://web.archive.org/web/20110406141724/http://www.naturebase.net/pdf/nature/management/lesueur.pdf|archive-date=6 April 2011|df=dmy-all}}</ref>

There are over 900 [[indigenous (ecology)|indigenous]] plant species in the park, many of which are [[endemic]].<ref name=CALM/> Rare or [[threatened species]] include the [[Grevillea batrachioides|Mount Lesueur Grevillea]], [[Acacia forrestiana|Forrest's Wattle]], the [[Hakea megalosperma|Lesueur Hakea]] and the [[Eucalyptus lateritica|Laterite Mallee]].

The park is the northern limit for [[Eucalyptus marginata|Jarrah]] and [[Corymbia haematoxylon|Mountain Marri]], both of which grow as [[mallee (habit)|mallees]] instead of the more usual tall tree form.

Lesueur National Park is under threat from the effects of [[Phytophthora cinnamomi|Phytophthora dieback]], a disease which kills plants and is spread through movement of infected soil or water.<ref>{{Cite book  | last = Dunne  | first = Chris  | author2 = Kilgour, Sharon  | title = Managing Phytophthora Dieback in Bushland  | publisher = WWF Australia  | edition = 3  | date = 2005  | location = [[Perth, Western Australia]]  | pages = 48  | url = http://www.dwg.org.au/files/ManagingPhytophthoraDieback.pdf  | access-date = 7 August 2011  | url-status = dead  | archive-url = https://web.archive.org/web/20111007204146/http://www.dwg.org.au/files/ManagingPhytophthoraDieback.pdf  | archive-date = 7 October 2011  | df = dmy-all  }}</ref>
