The deep purple blooms of the Great 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 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.
