Downy Lobelia - Lobelia puberula


Family: Campanulaceae - Bellflower family Genus Common Name: Lobelia Native Status: NativeDicot Perennial Herb Leaves:Alternate
Lobelia puberula - Downy Lobelia.
Lobelia is a large genus, with over 400 species worldwide; nearly 50 are found in North America. Most are herbaceous - as are all North American continental species, but a few African and Hawaiian species are trees or shrubs. The leaves are alternate in either a spiral or two rows on the stem. Most Lobelia flowers have an opening on the top of the corolla tube nearly or entirely to the base, and may also have side fenestrations. The corolla is typically two-lipped, with the upper lip having two lobes (usually erect) and the lower lip almost always three lobes (usually spreading.) The 5 stamens are joined together in a tube with the stamens exserted from the corolla, usually through the opening in the top of the corolla tube.

Lobelia puberula is the most common blue Lobelia in the Southeast.

Found in:
AL, AR, DC, DE, FL, GA, IL, IN, KY, LA, MD, MO, MS, NC, NJ, OH, OK, PA, SC, TN, TX, VA, WV, GS

The stem and calyx of Lobelia puberula are pubescent, the calyx (and pedicel, not seen in this photo) densely so.

This is likely Southern Lobelia - Lobelia amoena - rather than Downy Lobelia.
