I received this information from Matts Jopson, Director of Sales & Marketing.

Matts Jopson said:This is actually a strange variant of ‘Silverine’ that we found mislabeled amongst our old stock of Sempervivums. We couldn’t figure out what it actually is called, so we just decided to name it ‘Pinkerine’ to contrast its color with the original ‘Silverine’.

If you have any other ideas about what it could be, I’d love to hear them, because we do strive for accuracy in our listings.

Thanks,
Matts Jopson, Director of Sales & Marketing

It is unkown whether it is a seedling amongst the group of 'Silverine', or an actual variant of 'Silverine'.
In either case we cannot show the breeder as Sandy MacPherson, but it sure is a beauty.
