Tone Paw

What plants would go with Kangaroo Paw to tone down the native ness of this garden?
Hello, I planted a bed of kangaroo paws orange. The master, but is now looking too native and do not really adapt to the other 3 gardens nearby. In the other gardens we have a green cover (2 m in height) and Mondo grass. and other garden flowers have some beautiful plum blossoms pink. Any suggestions on something we can plant green amoungst the kangaroo paws to make it less native and draw in more of a traditional English Garden type. I was thinking maybe lavender, gardenias color but may be too mcuho so maybe? or just bright green herbs? I also want to plant something under / behind the peach trees as a kind of a 50cm – 1m headgear. any suggestions on this? Gardenia was thinking about that. all are in full sun per day at least half of the. any suggestions would be greatly appreciated!
I'm really not sure because I'm not very good at gardening, but because I thought you were an Australian man who I help. Perhaps a laurel hedge? Camellia Sorry I can not be of more help.
