I suspect we don't even have Viola odorata 'White Czar' in this country, and they're all misidentified white V. sororia plants. I wonder how many would-be violet lovers are turned off violets altogether when their first "sweet" violets end up being scentless impostors. Roy Coombs' description makes me wonder if there even is a true white V. odorata in the "Czar" series.
