Hi Ruud,
It's been suggested that this photo and your other one at the Nationale Plantentuin Meise (Brussels) might not be correctly labelled due to the colouration. Unfortunately herbariums and the like don't always have accurate labels and I am not familiar enough with the species to rule out this colour form, so I'm hoping @BigBill or @Ursula may be able to comment.
