First I am so sorry about the passing of your Mom tied up with this rose because your George Washington rose is no longer what it once was. What you describe is a hostile take over by the root system of this hybrid rose. The top part of the rose was grafted onto a hardier root system and after a few years the roots sprouted and the more vigorous growth from below the graft took over and killed off the original rose. This is called a sucker and if you catch the sucker growth early you may be able to cut it out but in your case it has overwhelmed poor George Washington. I suggest you dig it out as it will never bloom as you hope. Perhaps you can replace it with a rose of the same color that will still hold warm memories for you. If you chose another grafted hybrid tea rose make sure you plant it deep enough so that the graft is below the soil a few inches and is less likely to sprout and take over the upper part of the rose. Have fun rose shopping, and Keep Growing, Marianne Binetti
