Lobelia siphilitica

This showy perennial is usually unbranched but may exhibit some branching. The erect, 2-5 ft., stems produce lavender-blue, tubular flowers crowded together on the upper stem. Showy, bright blue flowers are in the axils of leafy bracts and form an elongated cluster on a leafy stem. Each flower is split into two lips - the upper lip has two segments and the lower lip has three.
