What kind of flowers come back every year but do not have any smell?

How about sunflowers? Or dahlias? Both fragrant-free and bright and beautiful

For perennials...Try Liatris,coneflower,butterfly weed,Coreopsis,Phlox.Coral Bells ,Sun Loving Hostas.

Thanks so much!!!

Bee balm comes in colors of the red Amily and coneflowers come in a variety of reds to oranges to yellows to whites.

Red Hot Pokers are a lovely plant along with cannas. Coleus will also add the purples you like. Orange butterfly weed is a lovely perennial. Not sure what growing zone you are inn but in warmer climates oleanders provide a pretty pink burst of color.
