San Diego Wildflowers

San Diego County is the most botanically diverse county in the contiguous United States. San Diego County is home to some 2,400 different kinds of plants, about half of which are annuals. This county alone is more diverse than many states, and it has even been identified as an international 'hotspot' of biodiversity. San Diego County has a combination of climatic, geographic, geologic, and floristic features that are unique in the USA.
