After doing a search on google.com, I found several references to this tree you speak of. The first three items I read on the subject were from Delaware, Michigan, and Rhode Island. The climate is a little different here. I am not well educated on the subject of fruit trees, but it is my understanding that pears may have difficulty here in North Texas.
Yes, Texas winters may be mild and confuse even native trees! The current winter season has been especially interesting. There is really nothing one can do to control nature. No one should try. Just work with her and you will have more success.
