You don’t always need a combination of many plants in one container. Repeat the same plant in many containers for more impact and simplicity. Here one geranium variety is repeated in many planters.
I like the repetition of geraniums in pots too, @JaniceS In fact, I was just about to post mine, but you beat me to it! Love your staircase and the boxwoods as well.
The geraniums do add a pop of colour that draws your eyes.
Great minds think alike.
