All of these wildflowers are naturally low-maintenance—they thrive in local climates, resist common pests, and offer seasons of blooms. By selecting a combination of annuals (like poppies and coreopsis) and perennials (like coneflower and yarrow), you create a self-sustaining garden that attracts pollinators and evolves beautifully year after year.
