1. Any one have information on Sempervivum 'Mark Waller'?
This photo from Mountain Crest Gardens catalog, has a rather unique coloration:



2. Regarding 'Tokajense', the semp database lists it as a form of marmoreum. Mountain Crest and a couple other sites list it as S. tectorum 'Tokajense'. Opinions on which one is correct?
Hen and Chicks (Sempervivum marmoreum subsp. matricum (tokajense))

I believe this to be actually 'Mark Weller' and you can see it on sempervivum-list.de. Named after the hybridizer. I think "Waller" was a typo. But I could be wrong.
And I agree, it does look interesting.

Thanks Tim, the plant looks attractive on sempervivivum-list.de
I searched on the whole name, so didn't find it due to the spelling difference, if I had searched just on "Mark" it comes as one of the options, lesson learned. Sempervivum 'Mark Weller' it is.

Here's the link:

Züchter: Mark Weller ( GB )
Translation for Züchter is breeder. GB probably refers to Great Britain.

I guess folks here have already dealt with the "will the real Tokajense please stand up" issue, in this thread:
The thread "Tokajense" in Sempervivum forum

Striking this one from my eventual MCG order.

Over the years many semps have come up with miss spelled names. It happens. Some times it is easy to trace, as in 'Mitchell's Gold', which was being sold as 'Michael's Golden'. That was an easy one, very distinctive coloring on this one.

Thanks Lynn for adding a Sempervivum Database record for S. 'Mark Weller'.

Still in its little 2" pot from Mountain Crest Gardens, it has a lovely blush of pink color, I took a photo and uploaded it to the plant record.

It has what I call a soft beauty about it. Lovely.

Updated 'Mark Weller' with two images taken today, taking on some nice inner green and pink watermarks, with outer colors an orangish-tan, and starting to chick. Temp today was 96F, back down to moderate lower 80s rest of the week.

Really like the colors on it Mark.
