There are more than 1,000 non-native plants in California that are naturalized (growing without cultivation). Many of these plants are invasive, choking out our native plants and reducing habitat quality for animals. We use various forms of management to control invasive plants on CDFW lands, including grazing, hand-pulling, and the judicious use of herbicides.
Local land trusts, nature centers, and conservation organizations offer field trips. Here are some field trip resources arranged by county.
In most areas, spring is the best time to view wildflowers, but the dates vary each year due to weather patterns. In general, higher elevations reach peak bloom later than lower elevations. To find out what is blooming at a given time, call or check the wildflower hotlines.
There are many places to see flowers throughout the blooming season.

The CDFW Native Plant Program
There are 640 rare, threatened, and endangered plant species in the 12 counties that make up the Central Region, according to the California Native Plant Society’s Inventory of Rare and Endangered Plants, 7th Edition. This represents 29% of the 2,177 rare plants in the state and includes plants on CNPS lists 1A through List 4. For definitions of the lists, see:
Sorry, but you shouldn’t pick them anywhere. You will enjoy them for only a short while, but by picking them you may damage the long-term health of the population. Besides, it’s against the law, even on roadsides. Take pictures instead!
Many of our wildflowers are annuals, meaning that the plants die at the end of the growing season. They produce seeds one year that sprout the next time the conditions are right. Our variable weather means that conditions are not right every year. Sufficient rainfall is needed at the appropriate times in the growing season, and temperature plays a role, too.
