My own contest, run by me, judging my containers - and the winner is this pot by the shed:
This container is closely modeled on the "Red, Green and Ice" annual combination offered by White Flower Farm this spring. The 'White Christmas' caladium and 'Dipt in Wine' coleus are their suggestions. I'm very pleased and will have no compunction about stealing their ideas again next year.
The runner-up is a similar pot with pink angel-wing begonias and white impatiens and without coleus. I love the dark purple of the begonia leaf:
Okay, and the loser is this poor little pot, which has some height and a nice trailing effect with the sweet potato vine, but whose colors are muddy and not so great. It started out looking okay:
...but by now it's looking a little raggedy:
Too bad - better luck next year!
