I have all of the above. I didn't know that there was a separate S. kirkii 'Blue' now that I think about it I may not have the S. 'Blue'
There are a lot of S. suffruticosa out there.
I have mostly species. Which I prefer, and many varieties of S. thyrsiflora and S.thyrsiflora
The "experts" have done a great deal of name changes, because they were not published according to the nominclature rules of the time. Which left us collectors holding the bag. It took me 36+ years to find out the name of one of my species, which is now called S. metallica, with purple/wine colored leaf sheaths and very blothched leaves thick and stiff.

Hi Norma!
I didn't think there were any of the kirkiis you didn't have? The blue form is pictured on the nursery of the Italian website which sells Sans, can't think of the name right now. You probably have this, yes?

The blue one, I have a S.'Super Clone'is it a blue one, I may not S. Kirkii blue, are they different?
There still may be some that I don't know about, so I'm not sure that I have them all at this time. Did you know that there is a plain green one. and S. aubrytiana may be part of that complex as well. So add those to your list. This is from memory, so look it up and be sure. I don't want to pass off bad names. I don't have all the species yet, so I'm always looking. Norma
