California blue bells are a species of flower native to southern California and can be easily grown in gardens or wildflower plantings. The name Phacelia comes from the Greek word phakelos for “cluster,” referring to the groups of flowers the plants bear.

The California blue bells grow up to 8 inches tall with triangular-shaped leaves and blue, bell-like flowers. The stamens stick out beyond the flower, resembling the clapper of a bell.

For optimal growth, California blue bells should be planted in full sun with dry, sandy soil and good drainage. They bloom best in cool, dry, sunny weather in the spring and diminish in the hot, humid weather of summer. Space plants 6 to 8 inches apart and stake them in areas protected from high winds. Propagation is done by seed, which can be sown outdoors in mild winter climates in the fall or as early in the spring as the ground can be worked. For earliest bloom, start plants indoors 6 to 8 weeks prior to planting outside as soon as the danger of frost has passed. California blue bells are great for informal situations and can be planted in masses for the dominant blue tones they provide. Other related species include Phacelia viscida and P. tanacetifolia. The scientific name of California blue bells is Phacelia campanularia.
