In Spring, you'll see Sydney in a certain purple glow around late October to early November as the Jacaranda Trees come in full bloom. Some places around the world may have Cherry Blossoms during Spring, but in Sydney, we have the Jacaranda Trees that signify that Spring is nearly over.
I've fallen inlove with the Jacaranda Tree since I've moved here as they're really beautiful up close. I'm lucky enough to work in a place where I'm able to see Jacaranda Trees as I walk to and from work.
