An art nouveau botanical conservatory set within a bustling metropolis of the 2050s, where bioluminescent algae illuminates opalescent stained glass domes, inside a serene oasis of exotic plants and augmented reality butterflies. Outside, skyscrapers tower with vertical gardens and solar-powered holographic billboards. The scene blends the elegance of Alphonse Mucha's organic curves with the sleek, sustainable aesthetics of solarpunk architecture, creating a harmonious balance between nature and technology.
