Hi there,
My husband and I are adding a outdoor firepit area with seating made from besser blocks. Ive attached the inspiration picture we are using to guide us. My question is what kind of plants would add good contrast or colour behind the seating. Im not looking for screening plants or plant hedges but rather something like a coastal type theme. These plants will be next to a colourbond fence. We get direct sunlight and part shade. We are located in Central coast so humid type heat in summer. Any advice would be great as we are novices when it comes to all things plants.

Current space.
