Generate an image of a delicate, vibrant watercolor painting featuring a large, central rose flower with soft pink and light blue petals, surrounded by smaller wildflowers and a variety of greenery. The background should be a soft wash of whites and pale blues with artistic splashes of yellow and pink watercolor droplets scattered around, suggesting a loose, airy feel. The composition should be slightly off-center, with it being the main focus and the smaller blooms and foliage creating an asymmetrical balance. The style should capture the essence of a spontaneous and expressive watercolor garden scene, with a sense of freshness and natural beauty.
