bay lobelia, Lobelia feayana

Bay lobelia is a small plant that is well adapted to roadside ditches in Florida. It's native of wetlands, but is particularly fond of damp areas where mowing might help control the competition. Where it thrives it forms large colorful patches, often described as a blue mist. It would be endemic to Florida but for one time it popped up in an adjacent Georgia location. Hillsborough Co FL, 1/24/13. Bellflower family, Campanulaceae.
