Create an image of a majestic iris flower in full bloom, standing gracefully in a serene riverside garden during early morning. The iris should have deep violet petals with intricate white and yellow markings. The garden is lush with verdant plants, and the river should be calm, reflecting the early morning light. The background includes a stone arch bridge partially covered in ivy and distant mountains bathed in a soft, golden glow from the rising sun. Use a classic, realistic oil painting style to bring out the rich colors and textures of the iris and the surrounding garden. The angle should be a mid-shot, focusing on the height and elegance of the iris against the picturesque scenery.
