Jason nice window boxes.
Hi Kate!!!!! I grow lots of these every year and even take cuttings to hold over in the greenhouse. I don't put any coleus out until it stays 50 degrees at night. They are very tender plants. I'm also in Washington State and think we may have similar growing conditions. I mix mine in containers like Jason, just bait for slugs they love the tender new plants.
This may help. I know you cant order from here but lots of good information on growing.
