The girls have a Rainbow Garden. It's made out of an old tractor tire that we rolled home on our walk down the 'farm road' one night. It was big and heavy and unwieldy and the girls thought I was a superhero for getting it all the way home. I kinda am.
We went to a nursery and let them wander and pick whatever flowers they wanted that were in our price range. They decided to make a 'Rainbow Garden' and walked around saying 'we have Red Butler, now we need Canary Yellow' and 'we can't find Buddy Blue!'. Eventually they found all the colors - even some white - and we all agreed that blue flowers *are* hard to find while green flowers really aren't necessary. And I've found that I really, really like verbena (the red, purple, and blue in the front of the picture).
We've even gotten a few strawberries out of the deal. It's so nice to look out the window and see a huge mound of color - especially since our flower garden is having a hard time with the cold weather we've had all spring and summer.
And it's princess approved.
