It is my favorite selection since I think it has the most promise for edibility. It’s hardy to at least 10°F, maybe slightly lower under ideal conditions, and that is based on our assessment of 1-2 year old grafts. Tender growth was surprisingly hardy and handled 20s with no damage. It is likely this selection survived the -11.8°F Winter under snow or it died back and resprouted.
Here’s some photos of the leaves:
