I know this was discussed several pages ago but i can tell you that 'Atroviolaceum' was NOT hybridized by Mina Colvin. This was one that was found way back in Correvon's or Sanford's collection. the Heimlich form was from Heimlich's Nursery in Woburn MA, probably some time in the early 60's. Mina's first two introductions were 'Raspberry Ice' and 'Silver Thaw'.
It is unfortunate that there were so many things with the 'Atroviolaceum' tag. It would have been better to call the Heimlich plant just 'Heimlich'. The two look quite different.
All of these should be pure tectorums so the one with pubescence sounds like a hybrid with montanum, not a pure tectorum.
OK my two cents!

Greg is correct about the 'Atroviolaceum Pubescent'. It would have a somewhat fuzzy/velvety leaf texture.
You can't really see it in this photo.

The photos at SMG shows the pubescents clearly when you click on the photo to enlarge it. http://www.smgsucculents.com/s......

This one is quite colorful, breeder unknown

This is the that seems to be credited to Mina Colvin (now showing as breeder unknow in our database). It has some beautiful color changes through the growing season, as you can see from the photos on sempervivum-liste.de

Yeah NONE of the 'Atroviolaceum's if they are true selections of tectorum should be velvet.
The second one looks NOTHING like 'Atroviolaceum'.
The plant from Mina Colvin looks like the real McCoy but it is definitely NOT her hybrid. The Heimlich form is smaller and has narrower more abundant leaves.
The picture of Atroviolaceum Heimlich in Helen's book is very close to perfect. It shows the very distinct narrower leaves and multi-leaved rosette. The picture of Atroviolaceum itself must have been taken after the spring flush of purple. The real Atroviolaceum should look like a paler version of 'Dark Cloud' when at its best color.
