Focusing on the The garden of Saint-Paul Asylum, Saint-Rémy (Van Gogh series), explain the Irises about the Flowers.
Irises Van Gogh made Irises from the irises in the asylum's garden.  The painting seems influenced by Japanese ukiyo-e woodblock prints due to its close-up views, large areas of bright color and irises appearing to overflow the borders of the frame. He considered this painting a study, which is probably why there are no known drawings for it, although Theo, Van Gogh's brother, thought better of it and quickly submitted it to the annual exhibition of the Société des Artistes Indépendants in September 1889. He wrote to Vincent of the exhibition: "[It] strikes the eye from afar. The Irises are a beautiful study full of air and life."A single iris is the subject of the second painting, smartly posed in the center.  Like rays of the sun, brush strokes radiate out from the plant. Iris, with one full bloom, may have been painted before Irises that was filled with blooms.
