Gandana - Afghan Leek

Has anyone tried growing gandana? It's a perennial allium much grown in Afghanistan. It's not in Crawford FG or Veg. I can hardly find anyone posting about growing it in Europe. An Afghan refugee friend has had some seed brought from Kabul, and we're going to try it. Afghans in exile miss it!

Here is someone growing in the Netherlands in 2008: https://bifurcatedcarrots.eu/2008/05/afghani-leek/
Here's a factsheet about growing gandana commercially in Afghanistan by the eAfghan Ag program at the University of California at Davis: https://afghanag.ucdavis.edu/fruits-nuts-vegetables/Vegetables/files/leek/afghan-leek-gandana-1.pdf
Here's an interview with Afghan refugees growing it in Vienna, July 2020. A summary translation by my friend can be found in the comment today 13/3/21 by HackneyMartian (me). https://www.youtube.com/watch?v=fNEskyLy8Uo
