Sprucing up with Flowers

I have been trying to get to the nursery to buy some flowers for my hanging and deck pots. With the contractor coming yesterday, I had to be home so today I am heading out to finally purchase my plants. Pink, white and purple are the colors I would like to go with. We already have several perennial plants in the pots so I am hoping I won't have to buy too many.

There is a beautiful arbor that we bought a few years ago and I just love it but I haven't been able to successfully grow plants on it. It sits in the shade of a large locust tree and there is also an underground sprinkler nearby that keeps the area moist so it doesn't dry out very well.

(Would like my arbor to have flowers like these!)

I was thinking of building raised garden beds in front of the sprinkler and putting hostas in there. That would shield the arbor from getting hit with water and then perhaps my climbing flowers will have a chance to thrive.

On a different note, my french doors are in! Yay!
