Van Gogh Vase of Irises. Oil painting on canvas from 1890. One of Van Gogh’s lovely vase and flower paintings capturing the heavy purples of freshly cut irises. Like Van Gogh’s still life paintings of sunflowers and poppies, Irises in a Vase captures a certain summer heaviness that add life and vibrance to the iris blossoms. A great gift for fans of Van Gogh, Irises, post-impressionism, and famous flower paintings.
