Lobelia siphilitica (Great Blue Lobelia)

  • Great lobelia is a clump-forming perennial which features an elongated cluster of light to dark blue, tubular, 2-lipped flowers with the three lobes of the lower lip appearing more prominent than the two lobes of the upper lip. The flowers arise from the upper leaf axils forming a dense terminal raceme atop stiff, unbranched, leafy stalks typically rising 2-3' tall. Its flowers are larger than other lobelias and have stripes on the tube portion. Blooms from July to October.
