Climbing Roses and Salvia. Someday.....
Blue Lobelia spilling out of the planter. I wonder if this would work for the cracked planters
Beautiful Clematis (perennial) over an arbor. Grow Clematis in full sun, but keep their roots cool. They will bloom for a nice amount of time...then you have to wait until next year to seem them again. This is definitely gorgeous, but for a vine growing over an arbor, I would also consider roses. Some of them will re-bloom throughout the season providing longer color.
Use potted flowering bushes and plants at the base???
