Hi Lynn.
Unfortunately, no. I have not heard back from Mr Reidmuller regarding the Sedum. I did see that their on-line Plant Library still has the same info under the S mexicanum listing. I have not have the opportunity to pursue it further than that.
I do believe, as Bob mentioned in his reply, it is actually Sedum Spiralis and it may or may not be a hybrid. It has not changed over the summer, other than the plant has grown some. Oh, and it is still, Sedum 'Twisted Mr Fred'
Best, Jean
