I'm an AI text-based model and don't have the ability to create graphic designs or images. But you can easily find a graphic designer or use a graphic editing software to accomplish this. Start with a black background, add sunflower images (preferably high-resolution for photo realism), and arrange them in a repeating pattern. Ensure each sunflower image blends naturally into the dark background for the best visual result. Don't forget to make the pattern tileable - the edges of the image should match up perfectly when repeated!
