When people think “fall colors,” San Diego County usually doesn’t come to mind. But there’s color to be found if you know where to look. These poplars were popping Wednesday near Lake Cuyamaca. Black oaks in the county mountains turn a vibrant yellow, & they should peak in early November. #trees

The floss silk tree (Ceiba speciosa) dresses up for Halloween with big, beautiful blooms - and spikes on its branches. It's a native of the tropical and subtropical forests of South America, but many floss silks thrive in San Diego County. This one is in Escondido. #trees
