    Lynn & Co: I received the plant I photographed and uploaded today from Sequim Rare Plants, titled only Sempervivum 'Atroviolaceum.' Let me know if it's in the wrong category... Thanks! MR

    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!
