zinnias larkspur and daisies 1928 Charles Demuth

The picture has something of this: flower, decoration, flora, nature, bouquet, floral, bright, arrangement, gift, cluster, vase, leaf, celebration, romantic, beautiful, season, love, blooming.
Perhaps it’s a watercolor painting of a bouquet of flowers in a white vase with green leaves and purple and red flowers in the bottom right corner of the picture.
