Hi Judith,
I am very pleased, no, stoked that Hortico is seemingly one of the primary sources for many of the older Austin's. In some ways they seem to have picked up the baton from Pickering Nursery. A decade or more ago, Hortico seemed to have some quality and customer service issues, but now they seem to be performing at a very high standard.
I myself have ordered three rose varieties from them for spring delivery, including a favorite that I left behind when I moved back west in the fall of 2016.
With respect to Cymbeline, she is a rose that I have often looked at and thought of growing, but as you know, she is rare and not in commerce. I know that Cymbeline is one of Jerri's Husbands favorite roses and that she and Clay have a mother plant. Perhaps there is a nursery that would agree to propagate it if they could acquire the appropriate plant material and if Jerri, or someone else with a healthy mother plant would agree to provide the wood or cuttings.
This is exactly what happened with the arrangements made between myself and Hortico for bud wood from Cressida, The Reeve, St. Cecelia, etc. An enthusiast, from California, who was a member of this forum contacted Hortico, a Canadian nursery, and said if I can arrange bud wood, would you propagate the plants. When Hortico agreed, they contacted me, a Canadian enthusiast, by email and hooked me up with the owner at Hortico and I sent the wood that summer. It took a few years, but now these rare, but exquisite rose varieties are back in commerce and available for sale in all of North America.
Antique and Modern Reproduction rose varieties saw a surge of interest in the late 1980's and the 1990's. As go many things in modern culture, OGR's at that time were trendy and Austin roses were new and fed into the OGR interest and trend. But now times have changed and gardening and rose growing in particular seem to be once again becoming an enthusiast's pursuit. So we are once again in an era when the rose enthusiasts have a responsibility and an oportunity to preserve worthy rose varieties from disappearing during this cultural lull in interest.
You are correct that up until when I sent them bud wood from my Cressida plant, Hortico was selling the wrong rose under this name. When they were advised of this fact and offered bud word from a mother plant of the real Cressida, they acknowledged their mistake and jumped at the chance to get the genuine variety back into commerce. I do not think you will be disappointed with the true Cressida when you get her and she begins to mature. Cressida does better grafted in my experience, so the grafted plants from Hortico should do very well. When she blooms, expect to fall in love and when you take a deep breath of her scent, prepare to swoon. I grew her two decades ago espaliered on a wall in a warm climate. She was intermingled with a plant of Sombrueil, the combination of which was to die for. Enjoy!
My two bits worth, cheers,
Rick
