Asexual propagation by stolons began in 2012 in Shasta County, California, USA based on plant growth habit, time of production and yield. Further propagation and testing was conducted in Huelva, Spain from 2015 to 2016.

Tests & Trials: The detailed description of 'DrisStrawFiftyTwo' is based on the UPOV report of Technical Examination, application number 2017/1987, purchased from the Community Plant Variety Office, in Angers, France.
