I spotted a beautiful plant with the pretty purple flowers in the market. The plant name is Scaevola aemula ‘Aussie Salute’. The shape of the flowers is quite unusual. It looks like the flower has been ripped into half. As it is half circular, this plant is also known as ‘Fan Flower’.
I still have this plant in a pot, but I plan to transplant it in a sunny spot in the garden.
