Joseph Banks Native Plants Reserve, Kareela
The reserve showcases a wide range of Australian native plants from around Australia in planted theme gardens including an acacia garden, sun-loving plants, rainforest, silver foliage garden, bush tucker, shade garden, fern garden and lily garden. The reserve also includes an unplanted natural area showing the original remnant Sydney sandstone vegetation. Over 600 plants are labelled with their botanical name. See the list here. 
The reserve includes most of the local east coast banksias including "Banksia aemula", "Banksia ericifolia", "Banksia integrifolia", "Banksia marginata", "Banksia oblongifolia", "Banksia paludosa", "Banksia plagiocarpa", "Banksia robur", "Banksia serrata" and "Banksia spinulosa". Western Australian species growing at the reserve include "Banksia blechnifolia" and "Banksia repens". For more on local banksias see and.
Banksia marginata
Banksia marginata, commonly known as the silver banksia, is a species of tree or woody shrub in the plant genus "Banksia" found throughout much of southeastern Australia. It ranges from the Eyre Peninsula in South Australia, to north of Armidale, New South Wales, and across Tasmania and the islands of Bass Strait. It grows in various habitats, including "Eucalyptus" forest, scrub, heathland and moorland. "Banksia marginata" varies widely in habit, ranging from a small shrub, high, to a large tree, tall. The narrow leaves are linear and the yellow inflorescences (flower spikes) occur from late summer to early winter. The flower spikes fade to brown and then grey and develop woody follicles bearing the winged seeds. Originally described by Antonio José Cavanilles in 1800, further collections of "B. marginata" were described as several separate species by Robert Brown in 1810. However, all were reclassified as a single species by George Bentham in 1870. No distinct subspecies have been recognised by "Banksia" expert Alex George, who nonetheless concedes that further work is needed.
