I've noticed recently some variation in the purpureas that turn up for sale at Lowes. Typically, during the growing season, we get the northern form of the plant at our NC Lowes stores. Lately, however, there seem to be some intergrade plants for sale there. It looks like French3z's plant is the southern variety, though I may be wrong. I can't tell exactly from the angle, but it seems to have the traits from the picture.
I'm curious where the plants are coming from. If they are tissue culture, which I would think they would be, the propagator is producing several different cultures.
