Identification
This native perennial has an erect stem up to 2 feet tall. Alternate, unstalked leaves are often lance-shaped as in (E), but are quite variable in shape. Elongating spike-like racemes of showy, blue, tubular, two-lipped flowers on short stalks arise from the tip of the stem. The upper lip has two erect or swept back petals; the lower lip has 3 larger, pointed petals which serve as an insect landing pad. Small, light blue or white patches are often present in the throat at the base of the lower petals (C). The lovely white striping on the outer tube (D) is sometimes, but not always present (B).
Grows in wet areas often near streams or standing water, flowering in August and September. Uncommon in wet areas on the floodplain at Fontenelle Forest and Neale Woods.
Other common names include Blue Lobelia and Blue Cardinal Flower.
The species name, syphilitica, was based on the false belief this plant was an effective treatment for syphilis.
Great Blue Lobelia’s showy flowers and tolerance for moist, shady sites has made it a favorite of many gardeners.
