I am doing my whole yard, have some ideas for the backyard, but last year, I planted flowers in front of my porch, just 5 in a row, and it looked plain, not filled in and plain stupid

. Here is a pic I just snapped outside, its dark sorry

. I circled the part in red that I need to place flowers, I want perennials, I want it filled in, and I want it to match, any ideas appreciated
Here is the pic!!!

Not sure what the flowers are on the left, but I am not too fond of them so will more than likely rip them out
