There are more than 1000 species in the Garden planted in such a way as to achieve natural beauty. Most of them are indigenous to tropical and sub-tropical regions.

Although small, the botanical collection includes members of the major plant groups such as Conifer, Fig, Palm, Gum Trees, Magnolia, Camellia, Azalea, Philodendron of exotic origin as well as the native flora. The Dawn Red-wood, the local Ailanthus, Crapnell's Camellia, Grantham's Camellia and Yellow Camellia provide rarity. The Norfolk Island Pine, Travellers-tree, Royal Palm and Asoka Tree provide distinctive features in form, leaf-shape, bark and fruit. The Garden is frequently filled with the fragrance of Roses, Mock Lime, Orange-jessamine, Kwai-fah, Chinese Privet and the White Jade Orchid Tree. Conspicuous flowers are produced throughout the seasons by Hong Kong Orchid Tree, Spider Tree, Wormia, Candlenut Tree and Kassod Tree in sequence; while autumn foliage is displayed by the Sweet Gum and Bald Cypress. Visitors can see all these trees identified with labels as they walk along the footpaths.

A Herb Garden is located in the southern corner of the Garden and the shrub collection is mainly centralised at the Fountain Terrace Garden where a regular display of colourful blooms is maintained.

A Greenhouse standing at the eastern boundary houses over 150 native and exotic species including orchids, ferns, bromeliads, climbers and house plants etc.
