Name of blue rose of sharron?

Does anyone know the name of the blue rose of sharon? Lowes had a few different oneswith no blooms so I didn't know which one was blue. thanks

There's Blue Chiffon with a fuller, almost double center and Blue Satin, a single with magenta eye. An older blue is Blue Bird with magenta center.

Hope this helps.

There seems to be some raving going on for 'Blue Satin'. I might be tempted myself.

thanks gardener guy. I just love this colour. Now to find one in Canada

There is a Rose of Sharon "sky blue" on ebay. I really like the color of that one from the pictures. Anyone have seeds for that one here? The seeds for sale on ebay for this one were open pollinated. That means they might not be like the parent plant doesn't it?
Thanks,
S
