The most common causes of blind shoots would be:

-the plant ran seriously short of water during shoot elongation.
-the shoots are coming off an old cane or cane stub that was damaged by winter or canker; I would think Mr. L would have been damaged to the ground in your past winter.
-the shoots are suckers from the rootstock variety (below the graft) and will not bloom until next year; most rootstock varieties bloom only once a year on canes that have been through a winter. Do you have two types of foliage/thorns on the same plant?

Just snip off a few inches below the tip, and I bet in a few weeks you'll see a bunch of buds. Sometimes it just happens. So ya gotta go cut it back to stimulate some new growth.

Michael's explanation is good. In some instances doing what Beth suggests works.
Sometimes removing the damaged portion that is growing the blind growth allows the bush to put its energy into good growth. If all I get is more blind growth after removing the damaged portion of the bush, I remove the bush and get a new one.
I've also found that a rooted cutting of blind growth produces nothing but blind growth so best to get a new healthy bush and toss the old one..

Rose midge are another major cause of roses that fail to bloom. I suggest you read up on the symptoms.

You may have over fertilized. Too much nitrogen can cause excessive foliage growth with few flowers.

What kind of fertilizer are you using? Are you using a high-nitrogen one with few or no micronutrients? Have you ever heard of humanure? It's perfectly balanced for all plants and especially roses - plus, it's free and ecologically healthy!

Thanks to all for the responses. I looked up the rose midge and I dont think I have it, thank goodness. The rose was transplanted last fall into a hole in forest loam with compost and bonemeal well dug in. I fertilized with liquid fish in the spring and gave it to the rest of the roses too and nobody else has had this issue. I did prune the stems as suggested and hopefully this will generate some new buds. Thanks again.

If the underlying cane stubs are damaged, trimming the shoots will not help. Do shoots coming from certain areas of old wood have smaller leaves than normal and blind growth? If so, you didn't prune enough in spring, and the plant needs to be forced to produce basals from further down. I am guessing this on the basis of reports that PNW zones 7 and 8 had temperatures near zero last winter. At temperatures somewhere between 10 and zero, canes of most hybrid teas will sustain internal damage, and the shoots they produce from these areas will never amount to anything. You probably already know this, but, since you didn't respond to the point, I thought I should raise it again.
