Becky--
I am pretty sure your yellow one is Dr. Seuss. I have been growing this one
for years. The fragrance in the evening is bewitching!
Dr. Seuss resembles Charles Grimaldi a lot--except--Dr. Seuss leaves have
serrated edges. One way to tall for sure. Your picture sows the serrated edges.
One other unique thing about the Dr. S. is it's growth habit.
It sprawls like a big beach umbrella. Flat-topped and wide. The blooms ARE huge!
I live in z-7a and have to winter mine over in my Shop. I trim it back a lot and then
it just sits there in the cool and dark. Always comes back... Gita
Here are a couple pictured from 2013.
Here is mine from Sept. 2013. (1-2-3). In the last picture--(2012) ou can see how the yellow
changes to apricot color as the blooms age. They usually last about 3 days.
