These annuals and perennials bear one-sided clusters of lobelia-like blooms in brilliant blue, violet, or white; blue and violet flowers are more striking because of a contrasting white eye or throat. Plants bloom profusely in warm shade or filtered sunlight. Graceful in hanging baskets or containers. Fine cut flowers.
