California bluebell

The California bluebell, scientifically known as Phacelia minor, is a desert herb native to the western United States. It is characterized by its blue or purple tubular flowers, which grow in one-sided clusters. This plant belongs to the genus Phacelia, which includes about 150 species of annual herbs found in North America and South America.12

Another plant sometimes referred to as California bluebell is Phacelia whitlavia, also known as wild Canterbury bell, which has urn-shaped blooms. It is important to note that the name "bluebell" can also refer to unrelated plants, such as Hyacinthoides species native to Eurasia, or Virginia bluebells (Mertensia virginica) in the United States.23
