Blue Lobelia

Lobelia siphilitica

[lobelia_siphilitica]

Peter Kalm, the eighteenth-century Swedish natural historian, reported that native Americans used this perennial as a remedy for venereal disease. Carl Linnaeus therefore named it siphilitica. Although grown in European gardens earlier, it was sold by Philadelphia nurseryman Bernard McMahon in 1804. Great Blue Lobelia grows to three feet and produces an elegant blue, sometimes white, flower in mid to late summer.
