Krista I really hope it is a sport too! I looked through my sweet pea photos, to see if I had any examples to show you, but I didn't take any, I pull the suspect plants immediately. If it happens on a light colored sweet pea, there is dark stripes, but on darker colored sweet peas there are white stripes. But, since DMV is so prevalent, you would think we all would have seen this type of pattern before on dahlias if it was due to DMV, so that is a point for the sport column 🙂
