I have Pineapple growing here, and it is by far the most precocious pear I have growing. It has only set a few fruit so far, it's only on year 4 for me. But it is twice the size of any other pear planted that year. Zero sign of FB so far. Our CH will vary here in our area. I can get over 600 CH at my place in a good winter, but that's because I'm at nearly 1,000 ft. elevation, and in an odd little microclimate. Most other areas here are more around 300 CH.
