Deb,
I don't know of any fellow gardeners that have been successful with overwintering Lemon Verbena, greenhouse or indoors.
She sulked inside the one year, even under my T5 lights...such a Princess, she is!
Have you read anything substantive about this coming winter weather? There seems to be a conflict of opinion between meteorologists.
I'll err on the side of caution, though & try to figure out the best way & best siting for my borderline plants.
It was never an issue on the Sammamish property, as I knew all the micro-climates. Plus, I didn't have to worry about any neighbours viewing my funky but functional shelters.
No room at this current location, but there are some rather extended eaves along the back. Might work well.
I detest losing plants.
Anyone else have success with overwintering borderline plants without a GH?
