Showbiz is pretty vigorous. I'd guess there's a good chance it will come back.
I can see that it was trying to make a new basal, in this photo.

As to Grade 1, and Grade 1.5 --- Grade 1 plants must have at least 3 good canes.
To be honest, I'd prefer a 1.5 Grade plant with really substantial roots, over a Grade 1,
with chopped-off roots.
I believe that a Grade 1.5 rose can still make a good plant -- if it is well-planted, and well-cared-for,
and is of a variety that has some vigor.

Yes, grading refers to the size of the plant when it was dug up to be sold.

Grade does make a big difference in the vigor of the plant. I can make just about anything still alive grow, but not everyone can do that.

I was rose buyer at a local retail nursery for a while. I did not buy in anything lower than Grade 1. People's success rates with grade 1 1/2 was much lower. They were cheaper, but not enough cheaper; and it's too discouraging to the average gardener to have a plant not do well. You paid money for it, and you expected it to grow and bloom. There's little consolation in it having been cheaper, and being a lower grade. It still disappointed you, and perhaps turned you off growing roses entirely. Our customers were much happier with Grade 1 roses.

I have planted Grade 1 1/2 roses and had them do very well, after a couple of years. Never the first year. I've had more never do particularly well. They don't always recover from being the runts.

The rose in your photo was probably a grade 1 when you bought it, but now that it's been in your garden grade doesn't apply anymore. Looks like it just plain didn't grow over the summer. Could be any of a number of reasons for it to not have grown, like not enough sun, not enough or too much water, not enough fertilizer, roots not spread properly when planted. The leaves look like they have drought scorch from not enough water, and the blackening on the canes suggests cane canker from incorrect pruning - leaving a woody stub with no bud at the end. When you prune, cut just above a bud. Woody stubs will just rot, they can't grow without a bud.

Like any other living thing, roses need proper treatment all the time, and if they're allowed to weaken they may not be able to recover even if they don't die, they may live for years but never recover. If this one doesn't grow nicely next spring, replace it with a good quality plant.

Thank you all for these information. This one along with 17 more roses were bought last year from Costco. Out of 18 roses only 5 survived and all of them are more or less in this sorry condition, no growth at all. I guess I give them one more year to grow or off with their heads next fall.

Have a great holidays.

Grading standards are set by the USDA. You can download it from their site.

I am wondering about a shrub rose. Those don't tend to have big dominate canes to start with. I bought some #2 Bonica (and didn't notice they were #2 until I looked at the receipt). I am wondering if I should take them back?
