The botanical drawings in the albums were in part made by other artists. For example, De Boodt commissioned 200 drawings from the Delft floral painter Elias Verhulst. De Boodt later lamented that they had not all been drawn from live models. It was in fact common practice to copy drawings and prints. The model for this drawing was an engraving by Adriaen Collaert from his Florigelium (c. 1562-1585).
