Autumn foliar color is scarce here, not because the weather is too mild, but because it is not such a priority within landscape design. A few species can develop such color as they do where autumn weather is cooler. Of course, some do not. Native California sycamore is a stately deciduous tree with striking form while bare through winter, but contributes minimal color.
1. Cornus florida, flowering dogwood is just beginning to exhibit foliar color for autumn. It performs surprisingly well in the Santa Cruz Mountains above the Santa Clara Valley.

2. Lagerstroemia indica, crape myrtle is also starting to exhibit foliar color for autumn. It may do so before the weather gets cool, as if it somehow knows what time of year it is.

3. Platanus racemosa, California sycamore does not know or care what time of year it is. It is more likely to yellow in response to hot and dry summer weather than to do so now.

4. Platanus X acerifolia, London plane tree is the sycamore with maple foliage. It is just beginning to yellow, but ultimately, does not do much more than that before defoliation.

5. Acer platanoides, Norway maple is the maple with sycamore foliage. This cultivar has bronze foliage through summer, so develops its yellow foliar color for autumn quite late.

6. Acer rubrum, red maple, like crape myrtle, can develop foliar color for autumn before cool weather, as if it knows what time of year this is. It defoliates relatively early though.
