One good example of his work as a flower painter is his "Offering to Flora", a visual poem that parallels the lyric verse of his time, in which he united his skills as portraitist and flower painter to produce one of the most beautiful paintings of the allegory of spring. The large canvas, painted in 1627, shows the goddess of the flowers seated besides a cornucopia of spring flowers. The painting adopts a Flemish compositional type and reveals an interest in the play of light on iridescent fabrics that probably derived in the style of Juan Bautista Maino. The offering to Flora and the pair of paintings "Still Life with a Vase of" "Flowers and a Dog" and "Still Life with a Vase of Flowers and a Puppy" formed part of the interior decoration of Jean de Croy's palace in Madrid. Jean de Croy, conde de Solre and Diego Mexia, marqués de Leganés, were Van der Hamen's greatest patrons.
