Here is the white stock. We also had some pink, but it didn't come up this year. My red hibiscus has it's first bloom on it. I had taken a pic of a hummingbird moth at the stock, but it didn't turn out.
I love the color of your Hibiscus. I think Netty is correct thats Phlox, Stock -Matthiola incana is a different plant. http://www.gardenstew.com/plantstew/23249
What a lovely photograph of your phlox CK - I'm a real sucker for white flowers!! The red of the hibiscus is really lovely.
Those two fotos are lovely to look at. I agree with Netty about the type of flower the white one is. Whatever it is though, it's gorgeous.
