California grape (Vitis californica) is a vigorous, deciduous vine that can be trained to cover an arbor or fence or serve as a groundcover if left unsupported. Its edible purple fruit ripens in late summer (though it is toxic to dogs), and its large leaves turn brilliant shades of orange and yellow in fall.

This fast-growing plant thrives with water but is highly drought-adapted once established. While it can tolerate heavy irrigation, excessive growth may require regular pruning to keep it in check.

California grape provides excellent cover for wildlife. Birds and other animals rely on its fruit, bees are drawn to its flowers, and it is one of the best plants for supporting butterflies in the fall.
