Bushland Species within the Garden
There is a healthy diversity of naturally occurring native plant species in the understorey within the five hectare planted area, as well as on the surrounding rocky hills within Olive Pink Botanic Garden. To date 135 bushland species have been recorded within the Garden, many of these being short-lived ephemeral species that come up after rainfall events.

Bindis (Scelrolaena species) and other saltbush family representatives (Atriplex, Chenopodium, Einadia, Enchylaena and Maireana species) are common understorey species in the Garden, while short-lived native grasses such as button grass (Dactyloctenium radulans), hairy armgrass (Urochloa pilgera), five-minute grass (Tripogon lolliformis) and native oatgrass (Enneapogon avanaceus) are prolific after summer rains.

Eight-day grass (Fimbristylis dichotoma) regenerates from tubers in the Garden after summer rains	Summer rains also produce carpets of ephemeral forbs such as tar vine (Boerhavia species)	Daisies, such as billybuttons (Calocephalus platycephalus) carpet the Garden after autumn rains

Summer rains also produce a carpet of ephemeral forbs such as munyeroo (Portulaca oleracea), red spinach (Trianthema triquetra) and tar vines (Boerhavia species), while winter rains lead to mass germination of daisies such as billybuttons (Calocephalus platycephalus), white paper daisy (Rhodanthe floribundum) and (pesky) bogan flea (Calotis hispidula).

Despite the invasion of buffel grass (Cenchrus ciliaris) onto surrounding hillslopes, there is still a good diversity of native shrub and sub-shrub cover on the surrounding hills. The dominant vegetation type is witchetty (Acacia kempeana) and mulga (Acacia aneura) shrubland with rock fuchsia bush (Eremophila freelingii), native fuchsia (Eremophila latrobei) and cassias (Senna artemisioides subsp. sturtii and subsp. helmsii) common in the low shrub layer.
