Looking for recommendations for trees/plants for my front yard

Hi everyone,

I’m located in Melbourne and looking for a couple of recommendations for my front yard.

Looking at replacing all the lavender bushes in front of the window. Something low maintenance, which won’t grow above the window frame. Ideally something nice and flowery, a shrub type is good too.

Want to plant medium sized tree in the middle of the front lawn. Also low maintenance, and flowery.

Not sure if I’ve included all the necessary details. But hopefully it’s a start. Thanks 😊
