One of the world’s centers of biodiversity, California has many species that occur nowhere else. A range of habitats exist here, from forested mountains to dry deserts. Most of the state is in a Mediterranean climate with mild, wet winters and warm, dry summers. In summer, many California native plants go dormant, losing leaves or limiting growth until winter rains return. During spring you might see our state wildflower, the California poppy (Eschscholzia californica), that dies or becomes dormant the rest of the year. Other plants have small, tough leaves to survive year-round, such as the Canyon oak (Quercus chrysolepis) on the hill.
