The gardens have matured since their opening, to the extent that some areas have had to be replanted after maturing trees and plants came to the end of their life cycles.
The New South Wales National Parks and Wildlife Branch of the Department of Environment and Climate Change has identified the gardens as part of the recovery plan for certain environments and species, including Cooks River clay plain scrub forest, Acacia pubescens (downy wattle) and Wahlenbergia multicaulis (Tadgell's bluebell).

Other plant species in the garden include pine, cherry blossom and azalea, which are present in the Japanese Garden.
Species such as Frangipani, Lavender and Sage are found in the Scented Garden.
Floribunda, grandiflora, petunias, garden roses and David Austin Roses are present in the Rose Gardens.
The Garden's woodland area has a thick canopy of foliage with tremendous amount of vegetation that would produce damp littered leaves and a moldy floor.
A remnant of Cumberland Plain Woodland, the woodland's structural form is an open-forest to low woodland with a shrub by understory.
