Long blooming, & lovely with masses of graceful, tumbling azure-blue half inch flowers. We love it for its toughness & how it so fancifully softens the edge of the garden container. How important for baskets & window boxes as well! Blooms forever it seems, often overwintering here in USDA Zone 10. Self-sows to grace your gardening world every year. How sad we were when this epitome of essential front-of-the-bed trailers began to disappear from nurseries! So for those of you (like us) who love trailing Lobelia, we are ever so glad to pick up the slack! Rich soil for prettiest show! To 6” x 6”. Some occasional color variation has been noted.
