You are so welcome! Sorry to hear about the storm. Did you get to see fireworks? We were so tired we didn't go. It rained early in the day and then stopped and started up again around midnight. Sure was a lucky break.
You could always stake the spent flower stalks until the seeds ripen and then collect them and cut the stalk. I wouldn't pull the plants out yet as sometimes biennials will surprise you and bloom again. You just never know!
When weeding, the best way to make sure you are removing a weed and not a valuable plant is to pull on it. If it comes out of the ground easily, it is a valuable plant.
