I have ordered roses from Greenmantle. In fact, Tipsy Imperial Concubine was one of them. Here's my photo of one of the blooms.
Rose (Rosa 'Tipsy Imperial Concubine')
All of my roses from Greenmantle are growing happily and are quite large now. The roses arrive, as Steve said, sans pot. The root ball is wrapped in plastic. I might have a photo somewhere of a new shipment of Greenmantle roses. I'll try to find it. They're much, much larger than Vintage band roses.
The best thing about buying these larger and older rose bushes from Greenmantle is that the roses have been growing long enough to bloom and to prove they're the right rose. No possibility of mislabeling, which is rapidly becoming my biggest complaint about mail-order roses. Two more of my latest Rogue Valley purchases have proved to be the wrong rose.
