Blue Lobelia, Lobelia dunnii serrata, is a pretty little perennial with lots of little blue flowers. The plant stays low, around a foot tall. It grows in wet spots in Southern California. Use as a small scale groundcover in among rocks where there is moisture. Good for sun or part-shade. Our mother plants have survived here for years with total neglect in wet and then dry conditions.
