As Professor Bol pointed out, loc. cit., the pot marigold and the white rose on the left are identical to those in Bosschaert's flower piece of 1609 in the Kunsthistorisches Museum, Vienna (Bol, op. cit., p. 60, no. 10, pl. 7). The present picture cannot, however, have been painted before 1614 as until that date the artist always placed his monogram to the left. Bol implies a date of 1614/15 at the end of Bosschaert's period in Middelburg. The recurrence of the same flower in pictures painted years apart is a characteristic of the painter's oeuvre
