The large, lavender bloom (1.5 inches) was the first thing that drew my attention to this Spurred Butterfly Pea (Centrosema virginianum). On closer inspection, I found the growth at the top of the flower to be most curious.
After a bit of research I learned the “spur” is a uniquely formed sepal that is actually the lower lobe (but the flower opens upside down). Presumably, this distinctive twist assists with pollination, as the white line in the middle is a nectar guide (a sort of directional arrow for pollinators, “Good food here”).
