From the Missouri Botanical Garden (including a misspelling), http://www.missouribotanicalgarden.org/PlantFinder/PlantFinderDetails.aspx?kempercode=a613 » “Wishbone flower is a bushy annual that typically grows 6-12" tall and is noted for its ability to bloom well in shady conditions. Species plants feature two-lipped, tubular, trumpet-shaped, bicolor flowers with broadly 5-winged calyxes. Species flowers are pale violet with dark blue-purple lower lips and a yellow throat blotch. Cultivars expand the range of flower colors to include shades of burgundy, pink, rose, lavender and white. A pair of stamens unites at the anthers in a shape resembling the wishbone of a chicken, hence the common name. Toothed, oval, light green leaves (to 3" long). Genus honors Olof Toren, an 18th century Sweedish chaplain.”
