And here it is with a bit more webbing. Marilyn, looking at the tag for your Xandra, it not giving a name of S. 'Red Cobweb', but just a description of the leaves being red at some time during the year. Just like one of the photos in Peter's link above.
Marilyn's growing conditions are quite unique from many of our growing conditions. She is at a very high altitude with extremes in weather year round, with very intense sun during the winter.
Chris's conditions a very different from Marilyn's. The two photos are just 2 weeks difference in time.
If happy and healthy this is what it can look like in Marilyns growing area of Denver, CO.
This is Sandi's photo.
In my area it looks more like yours Peter, I think our weather conditions are very similar.
