Well, believe it or not, it's Verbena Belle epoque - that's its name, its one of a bunch of trademarked, patented new varieties under the grouping Trixi from a company called Selecta.

By Googling I've found that that's the name given to a set of Verbenas with a particular colour combination that is being offered for sale. Verbena Trixi 'Belle Epoque' is a mixture of red, white and blue flowering verbenas.

More Googling tells me that "Belle Epoque" refers to a period of European social history that ended with the outbreak of the First World War.
