The flora within Mantenga Nature Reserve has not been thoroughly investigated yet, but the combination of highveld and middleveld climate results in a wide range of indigenous flora.
Due partly to other forms of land use prior to the establishment of the reserve, there are a number of exotic plants within the reserve, including guava (Psidium guajava), Lantana (Lantana camara), bugweed (Solanum mauritianus), black wattle (Acacia mearnsii), pine (Pinus patula), gum (Eucalyptus spp.), and jacaranda (Jacaranda mimosifolia).
