Desertbells (Phacelia campanularia) is an annual in the Waterleaf family (Hydrophyllaceae). Sometimes it is listed as California bluebells; always check the botanical name because there are many species of phacelia available. Desertbells leaves are light gray-green and oval. The bell-shaped flowers are deep blue with white stamens. It blooms from February through April in the desert, providing a much-needed early food source for pollinators. In cooler regions, it blooms from spring through early summer. 


In the wild, it is endemic (limited) to the Mojave and Sonoran Deserts in California. As an easy-to-grow annual wildflower, however, it is commonly found in native wildflower seed mixes. 

After the rainy season begins in autumn, scatter the seeds onto sandy or rocky soil. Good drainage and full sun is best. Desertbells are beautiful growing in a patch, or mixed with California poppies, golden blazing stars, or creamcups (Platystemon californicus). Allow the flowers to produce and drop seeds for more flowers next year.
