Todd, thanks for the enjoyable and thorough info on hardy roses. I should add a couple to my garden. Hardiness is not quite as much of an issue here, but easier is better :0) and I'm right on the Canadian border, after all.
I had Morden's Blush for about five years and moved it several times. it slowed up but lived and had the most beautiful delicate pink blossoms. Finally moved it to a large planter pot (24" across and the same deep, buried to the top four inches in dirt, full sun) and it promptly died. I was so bummed. It had survived being planted in miserable soil, dying back to a twig, and then, having planted it in what I thought was near perfect condition, it croked over winter. I found another one and replaced a Marie Bugnet that I didn't care for in the back yard. Have my fingers crossed. tough little rose. I also have had a Morden's Fireglow that has thrived and grown to at least 3'. they look like real roses (almost), not the wimpy rugosa's you see, whose blossoms last about five minutes. We have fairly long winters but only gets to -20 briefly. Very adequate snow cover. No special treatment.
