Fernglen's specimen in full bloom, 23Nov2014 (compare to the earlier photo I took on 12Oct2014 where it is just budding). A relatively young tree of about 30 years (planted in 1991 as a "specimen" tree, so probably had a few years on it before it went into the ground). Only the East-North quadrant had any flowers, and none on top of the tree. Based on that, I'd better stop trimming the lower branches off my one at home!

Thanks to dayne laird for sharing this photo!
