Yellow is often the default color for native plants because of carotenoid pigments, which are efficient to produce and when paired with ultraviolet nectar-guide patterns, makes these flowers highly visible to bees and other pollinators. In garden design, yellow-blooming flowers like goldenrods, rudbeckia, and sunflowers create the foundation of stunning, reliable color palettes. Enhance with the addition of their complementary partners: asters, liatris, and lobelias to create a combination that vibrates in the eyes of humans and insects alike.
