A neighbor to one of my elderly clients had a gardenia bush transplanted. It doesn't look so good. The leaves didn't yellow, nor have they fallen of. But they look grayish and dry. I scraped one of the stem, removing some bark and found it still green. They planted in November, I thought it was a little late in the year. What can I do to save the bush, for the old lady?

If you mean gardenia, check the following articles for possible diseases. Sooty mold is a possibility:
Otherwise, you might be right that it was planted a little late, but there's not much you can do now. You will have to wait for spring and hopefully it will get better established then. It may also just be a symptom of cold weather exposure, which the plant should recover from in the spring.
