This lovely flowering plant is not the hybrid "Debbie", which is pink with branched inflorescences. For comparison check out the images on this page.
Graptoveria (XGraptoveria 'Debbi')
Unfortunately I am not quite sure what to call it. Do you have any other information which might shed light on the ID question? Otherwise I would like to suggest that we move the image to the generic Echeveria entry here.
Echeverias (Echeveria)
Please let me know what you think. I would be happy to propose the image be moved if you agree.
