Both have leaves that are serrated, and both handle heat pretty well, but since they are related, one would expect this. Dr. Seuss does well in my North Texas heat.

Thank you, Carrie. What would you consider to be the main difference and which one do you prefer?

I did not really notice that much difference, but Dr. Seuss is my favorite brug of all. If I could have only one, it would be the good doctor. I had the first inground one right outside my patio by the pool and the fragrance was so delightful. Many blooms adorned this brug for a long period of time............... I enjoyed this very much.
