Short Description of your Research or Creative Project (700 characters or less)
California poppy (Eschscholzia californica), the state flower, varies in lifespan and phenotype across its range. It's widely used in restoration, yet local adaptation is poorly understood. We conducted two common garden studies in coastal and inland California using seeds from seven locations. After greenhouse germination, plants were grown in Santa Cruz and Davis. We measured survival, growth, reproduction, and leaf traits. Results show evidence of local adaptation in fitness (survival and seed production), though not always in morphology. This suggests local seed sourcing is crucial for maintaining genetic diversity in restoration amid climate change.
