I'll bet you wrote the names down correctly, as you received them. Pass-along Iris, and club sale Iris aren't always reliably named, despite good intentions.
When our club has their sales, we have digs at various member's gardens. The digs are really a social event where most of the members sit chatting as they are labeling the Iris. Let's just say, some folks are more focused than others.. Also an unfamiliarity with a variety, can lead to mis-spelling or mis-hearing a name. As an example, I got "Arkansas Rounder" from one of our sales, and it is in fact 'Ozark Rebounder'.
I would guess your "Florent" is one of the ones you mentioned. When it blooms, you'll have a head start in it's ID. "Blue", however, will most likely be more difficult to pin down. It could either be part of the name, or just a description. When you post pictures, we are here to help
