This photo was sent to me by Carla Lankow who saw my plea for help in identifying my photo labelled 'Sedum cyaneum (1)'. Here is an excerpt from her email:
I received S. cyaneum from Bob Putnam of Kirkland WA at least 30 years ago. At the time Bob told me it was a start from England and was the true S. cyaneum. I know he corresponded with Ron Evens so I assume it came from him. Bob also said that Sedum ewersii var. homophyllum was often sold as S. cyaneum. I think what you have is S. ewersii var. homophyllum. I have received that plant many times as cyaneum, raised it from seed listed as cyaneum etc. I still have one tiny rosette of my original cyaneum from Bob Putnam. I have attached a rather poor photo of my plant taken a few years ago when it was in better shape. I now only have one tiny rosette left. The leaves of the true S.cyaneum are narrower than S. ewersii homophyllum, which I might add looks very little like the type of S. ewersii. S. ewersii var. homophyllum looks more like a thin leaved plane blue green (no pink) version of a S. pluricaule. Check out plates 100 & 101 in Ray Stephenson's book and the photo on page 284. What puzzles me is that your photo shows a plant in full flower and in all the years I have had S. ewersii homophyllum I have never had a flower. (Thanks Carla!)
