Generate a vibrant and harmonious mural that celebrates the cultural fusion of Puerto Rico and Texas through the language of flowers and animals. Depict several pairs of symbolic elements, such as the Puerto Rican hibiscus and Texas bluebonnet, the Puerto Rican parrot and Texas mockingbird, the coquí frog and Texas horned lizard, and more. These pairs should seamlessly intertwine, representing unity and coexistence. The mural should also include a rich landscape merging elements of Puerto Rico and Texas, along with discreet cultural symbols like the Puerto Rican flag and Texas star. Use a vibrant color palette that reflects the natural beauty of both regions. Encourage viewer engagement with hidden details or interactive elements. Finally, add informative plaques or QR codes to share the stories and cultural significance of each featured element, conveying the message of cultural harmony.
