Australian Banksia Flower

Australian Banksia Flower

With 170 species and all but one endemic to Australia, Banksias are some of the most iconic Australian plants. With their distinctive flower pods and spikes they are easy to distinguish, and some of them are large and spectacularly colourful. They got their name from the English botanist Sir Joseph Banks, who collected the first specimens and took them back to England after the first expedition of James Cook in 1770. Here is some information about their pods and flowers and a few species found in Australia like Banksia marginata and others.

Banksia Flower and Banksia Pod
The most distinctive features of banksias are their flowers and pods. The flower spike actually consists of hundreds or even thousands small flowers that produce a huge amount of nectar. Young spikes are colourful yellow, red, pink, orange or violet, depending on species, while the older spikes get dull in colour and in some species loose the flower parts with aging. The fruit is a woody follicle that consists of valves that enclose seeds. In some species the follicle splits as soon as it’s mature, but in most species the follicles only open after bushfires.

Where to See Different Species of Banksia Flower
Other characteristics, such as leaves, and the size of the plant, vary between different species. Some can be small scrubs while others can grow up to 30 metres high. They commonly grow on coastal areas and not too far inland, as they cannot do with less than 200mm of rainfall. There are therefore distinct geographical regions where banksias occur in Australia. The most famous with about 90% of all Banksia species is Western Australia. This is also where you find the most colourful versions like reds bright oranges. The other region, eastern Australia, has less species and they tend to be mostly yellowish in colour. The third region, northern Australia, contains only one species – tropical Banksia – the only species not endemic to Australia as it is also found in the tropical New Guinea.
