I was looking at this

http://www.hpshertsgroup.org.uk/shows.htm

At the bottom right of the page is a photo of a chrysanth marked
"un-named", which is what I have fond memories of growing in our garden
in the early 1950s. I have e-mailed the lady in charge of the national
collection, but wondered if anyone here might know where to get
something similar. I'm not even sure what type it is.
Any pointers much appreciated
