Identification | Southern Rockbell is a slender wisp of a plant that may grow to 1.5 feet, the stems single to many. The leaves are linear. The flowers grow on slender stalks, are 5-8 mm long, pale to medium blue, tubular with lobes generally spreading. Without the flowers, the plants almost disappear and would be easily overlooked. | |
