Zuzu ...
Greenheart Farms bought Tiny Petals and Nor'East and I believe is also the primary distributor a lot of the Frank Benardella roses. They have re-named some of the roses they are distributing including deVink's 'Cinderella' and Ralph Moore's 'Earthquake'. GH Farms is selling plugs to both small nurseries and the big box store producers and are not selling any of the roses retail or mail order.
I have found several florists selling Kordes miniature roses, but not in the super markets.
@JulieB, I don't recognize the rose in your photo, but I do know it is not Jean K. The bloom form is too globular. I am fairly certain it is not a Bennett rose.
Smiles,
