It was so interesting to read all of your suggestions. Originally, I was really leaning toward Professor Einstein, but when I read Neal's comment about the weak stems, I decided to go with Barrett Browning. The thing that puzzles me about BB is that in some pictures the cup is a beautiful deep orange, but in other pictures it is more of a yellow-orange. Is that because of the quality of the soil, or the use of fertilizers, or the age of the bloom? And after reading Sally's mom's comments, I think I'm going to have to get some Professor Einstein too at some point. Thanks again everyone!
