Where have all the flowers Gone?

Don't you just love a before and after? I was looking at some of my older pictures and I noticed this one. I was just so eager back in April to get some color on my deck that I think I created a monster. They are all perennials in the barrell except for the purple pansies. All I have done, up until now is just water them. I took the after picture yesterday. I am going to have to remove a few of the perennials, you just can't see them anymore. I must say the second picture does make the plants look overgrown, but in real life they look much better. I so under estimated how tall that back plant would get! Now I just have to find the right place to replant the perennials.
