Downy Lobelia (Lobelia puberula)


August 25th, 2012. Downy Lobelia (Lobelia puberula) – at least that’s my conclusion. I don’t know lobelias very well but this identification seems to fit the characteristics of these plants we found growing on the east-facing side of the dam at Pond 6A in the Piedmont National Wildlife Refuge in Jones County, Georgia.
There were just a few plants growing on the south end of the dam. They would have gone unnoticed if it hadn’t been for the flash of blue as was drove over the dam. The plants are in the center of the photo just a little above the edge of the pond

The arrangement of the flowers around the ‘downy’ stem. I’d never really noticed until this year that the flowers are arranged in a spiral pattern up the stem.

Lobelia puberula (Downy Lobelia, Hairy Lobelia) is native to the United States, where it’s found in states southeast of a line from New Jersey to Illinois and southwest to Missouri, Oklahoma and Texas. In Georgia, it’s found in many counties throughout the state but more frequently in north Georgia and in southern counties.
