My husband and I have been invited to dinner at a co-worker's house. There are about 6 couples in total attending. The email invite sounded semi-formal, certainly not casual.

I asked the host if there was anything I could bring. The reply was, "No, I think my wife has everything taken care of." Normally, I would show up with a bottle of wine after that response. However, you don't show up at this particular house with wine. The husband is a wine connoisseur. He works part-time in a wine shop, and is the resident wine expert around the office.

Is it rude to show up empty-handed? The only other thing I can think of to bring is fresh flowers. Any other ideas?

take a bottle of crown royal

Flowers or a plant would be nice. Fancy hand towels are nice, as would a bag of nice coffee or tea.

Do you know if your co-woker has a favorite wine? If so, there's nothing wrong with springing for a bottle of it.

Flowers are fine. And if he loves wine that much then do not worry about bringing some. People who love it that much love to find new types, or they love it even more when people don't know much about it and they can teach others. You can get them a nice bottle, and tell him you don't know what you are doing. He will love to tell you all about it and he will love you after that.
