You are right, Myriam, Google searches are quite confusing. It seems to me that when they do not find enough of the exact search, they add related items/pictures.
Of course, I can be totally wrong - just that I was told Miss Willmott must be bicolour (like mine: apricot and red), but I have also seen two contrasting shades of pink being called Miss Willmott as well by the magazine of the RHS.
The seed offer is open to you as well!
