We had our first crop of these last year. Really delicious - similar to potato but with a nutty flavour.

No one responded so I will. I do not know for certain. I shop at farmer's market where 2 organic farmers grow and sell these. Both know I grow much of my own food. The guy I normally buy these from never suggested I plant any.. He had ended for the season and I purchased from the other grower. She was telling everyone to plant some of what they buy. HOWEVER she often sales pitches to clear out stock. Also they are zone 4 - 5 -along the river near Kamloops.. I'm at much higher elevation in an unpredictable area. I long ago quit buying zone 4 plants due to cold snaps that hit every few years. I'm going to try a couple roots this fall if I can get them in this week. (end Oct, 1st of Nov -the next snow might stay). If you have access to them I suggest you try a few too. All the local growers who are at warmer elevations than I start their garlic in the fall and say it needs the extra growing time. These may need the settling in time too. Trial and error is the best bet in these climates. I'm on a hillside and after 30+ years still marvel how some plants do well in one area but not 10-15 meters away. I think it's related to underground moisture. Good luck!
