In his Nov. 20, 2012 post, Stan McKenzie describes a six-year-old Croxton pink grapefruit tree with a crop he estimated at more than 200 fruit, ripening around October–November, and says people liked its flavor. He suspects the tree may be Thompson pink grapefruit; this is an unverified identification, not established parentage or synonymy. His separate recollection of 14°F refers to the January morning he obtained a budstick, not a Croxton tree exposure.

The thread was started by Citradia on Oct. 25, 2015. Reply #2 (Dec. 7, 2015) calls Croxton a pink grapefruit with general grapefruit flavor, places its origin in Columbia, South Carolina, and repeats survival in the teens; the reported 14°F survival without protection is explicitly hearsay, with no identified tree or exposure details. Reply #6 (July 30, 2019) corrects the title's “Crocston” spelling and attributes a seedling origin in Columbia to Dr. Robert Rodney Croxton, but does not identify parentage. Reply #7 describes Ruby Red grapefruit and is not evidence about Croxton.

This citation is for Gregn's Croxton-relevant reply #11, posted Mar. 8, 2008, in a thread started by Dutchie in 2005. Gregn repeats an unspecified grower's report that Croxton endured at least −10°C without harm; this is not a documented trial by Gregn, and no exposure site, date, duration, rootstock, or protection is given. Separately, Gregn says he had a Croxton planted outdoors in ground in North Vancouver with minimal protection and hoped it would produce fruit; he does not report that this plant experienced the cited temperature or produced a crop.

Summary from transcript: English auto-generated captions retrieved for 0:00–0:46 of the 0:47 video identify fruit from McKenzie Farms and Groves in Scranton, South Carolina, as “Croxton Pink grapefruit.” At 0:21–0:29, the dialogue attributes its origin to a retired college professor in Columbia who raised it from a seedling and describes it as nearly seedless; the captions render “seedland,” so that word is not independently verified. Speaker attribution for individual lines is unclear. The video supplies no measured fruit traits, flavor notes, temperature exposure, or damage report.
