The deep purple blooms of the Blue Lobelia offer a welcome contrast to the yellows and greens of late summer. Pairs well with Black-eyed Susan and Fox Sedge. Looking to attract bees? This is a low maintenance, moisture-loving plant that will do just that. Flowers late in the summer into the early fall. Does well as a border addition along with other shade-loving plants, or in full sun.

We also sell Cardinal Flower.
