These easy-to-grow annuals bring lovely shades of blue to the spring garden. Sow in well-drained soil in fall or earliest spring; or sow in pots and transplant while seedlings are very small. Give some water to extend bloom season. Especially showy when combined with California poppy (Eschscholzia californica), sticky monkey flower (Mimulus aurantiacus), and other heat-loving annuals.Phacelia tanacetifolia
