Also, if you bought from a seller who is online and keeps an electronic catalog, you might search through it again to see what cultivars they sell that might match? It is possible it wasn't a catalog cultivar, or that they've changed inventory, but it might still be a current offering that matches. I know I'd check out the ones people have mentioned, to see if it was in the seller's inventory, and if not, I'd re-check the rest of their offerings in search of a match.
