Lobelia siphilitica

Lobelia siphilitica, the great blue lobelia[1] or great lobelia,[2] is a plant species within the Campanulaceae family. It is a herbaceous, perennial dicot native to eastern and central Canada and United States. Growing up to three feet tall, it lives in zones 4 to 9 in moist to wet soils. It produces a spike of zygomorphic flowers in the late summer.

It blooms from August to October.[3] It is a short lived perennial (with each plant living for only a few years).[3]

Although self-compatible, a flower is unable to offer pollen to itself and it must be pollinated by insects (primarily bees in the Bombus genus).[3]
