MoBot says: "Only reliably winter hardy to areas where winter temperatures do not dip below 0 F. In USDA Zone 5 (and possibly Zone 6), it is strongly recommended that the corms be dug up in fall and stored over winter in somewhat the same manner as for gladiolus (but do not allow them to dry out completely)." They'll be the better for digging anyway; they tend to push themselves out of the ground from year to year. Digging and replanting every year insures better bloom. Nell

The photo enlarges for me. It opens in a new window so maybe a popup blocker is stopping it for you. Hmm...I can't think if Annabelle rings a bell for me or not right now. My brain's a bit slow today.

I pinched the leaves and they have a little scent so maybe it is some kind of herb. It's not too far from the area where I cleaned out my seed box last year. I tossed a lot of old seed to see what would come up. I'll leave it for awhile and see what it does. I've never grown tansy. No hummingbirds yet here and my honeysuckle doesn't have many blooms to attract them. It has lots of buds though. The phlox does a pretty good job by itself keeping the weeds down. I have to pull a couple dandelions and a little henbit out of it every year but not too bad. I started that whole bed from cuttings that I rooted myself so I'm proud of it. : )

First is Jewelweed. Really good for butterflys and hummers. Also great to spread on your skin if you get poison ivy. Always try on your skin before using to see if you have a problem with the gel. Second is a type of dock. Use a long knife and cut the roots way underground. If the root turns yellow it is similar to the burdock that you can purchase in many grocery stores. 3 I am not certain but appears similar to Virginia Bluebells. However you have a much worse problem at the base of the picture, vinca. Vinca will take over everything including climbing trees and will with time be the only plant there. We have it across the street and other than providing cover for a few creatures there is no use for it. 4-5 Your plant may be lesser celadine because you mention flowers. Rather than getting rid of the things you have pictured most would be trying to divide to have more to plant.
