The fine painting of flowers demands considerable discipline, because the passing of time is an important challenge. A flower is always changing. To capture the moment, Pieter Wagemans bypasses the use of underpainting and paints each flower in turn, 'alla prima' until the painting is finished. Sometimes he needs a whole day for each flower, other times only a few hours. Often the flower compositions never existed in reality because the flowers were painted one by one over several weeks.
