Hmm..not sure. I think my plant might be a little taller and I don't see the yellow accents on the flowers. Still, that was one I had not looked at yet, so kudos!
Umm...I was looking at the ISB Atlas of Vascular Plants to form my opinion. It occurred to me I should check on our own Plant Database. But the picture there has pretty vivid pink-red flowers. Is that right?
