California Bluebell (Phacelia minor) is a charming annual in the forget-me-not family, featuring striking lavender to deep blue-purple, bell-shaped flowers. Blooming in spring, the flowers form clusters atop reddish stems that reach up to 2 feet tall, often gracefully drooping at the tips. The plant’s dark green foliage provides a beautiful contrast to its vibrant blooms.

California Bluebell thrives in full sun and well-drained soil, making it an excellent choice for low-water landscapes. Highly drought-tolerant, it attracts a variety of pollinators, including bees, butterflies, and sphinx moths, adding ecological value to any garden.
