Is this just another name for Silke's Dream I wonder?

I've also enjoyed x John Whittlesey. It's survived several winters in zone 8, including down to 15 degrees F. it doesn't bloom nearly as strongly as S. darcyi in my summer heat and shade, but it does have much better form than S. darcyi, and retains some of darcyi's unique leaf fragrance.

I doubt it's the exact same as Silke's Dream (which I haven't grown). I bought mine from John Whittlesey himself, when he ran Canyon Creek Nursery. He told me (over the phone) that a nearby California grower developed it and then named it after him. Silke's Dream seems to have been developed in Texas, according to online catalog descriptions, though they may be too similar to tell apart, since they share the same parents.

I have x John Whittlsey also and it came from Canyon Creek also. Mine has not done so well, struggling, but it's being moved now and I'm hopeful that it's going to do as well as the one pictured...that's a beaut!

My John Whittlesey has performed well through 112 degrees
but it does not bloom as well as "Silkes Dream" the other
hybrid of similiar parentage is "Scarlet Spires".
Some of my other hybrids from "Silkes Dream" have performed
equally as well.No hybrids from "John Whittlesey" yet.
John does seem to have more of a red flower than that of
Silkes orange.It would be nice to grow Penny's Smile"
some day.
