Flower of the week: White balloon flower

I've been so busy working on the house that I forgot this week's flower of the week--a white balloon flower with a double blossom.

While I was mixing a batch of thin set for the tile, I noticed this lovely flower starting to open. I followed it throughout the day; each photo was taken about 4 hours apart.





I bought three small pots of these last weekend, but I love them so much that I might need to go back for more.
