Look no further than Blue Lobelia, an annual whose flowers that are a true, vibrant, beautiful blue that blooms continuously throughout the summer but is easy to care for, and does well in the ground, containers or window boxes.

When these plants are in bloom, they look spectacular and produces an impressive amount of color for all gardens.
