I have been looking for a Garlic that will over winter in zone 6b and survive a sudden warm up.
Review: bogatyr garlic https://www.groworganic.com/bogatyr-garlic-conventionally-grown-lb.html
I planed them in the fall. EVERY single one made it through the winter and actually acted like they liked it.
And we had an early hot spell, worse than last year, and they are still going strong!
I am so looking forward to "Better have your fire extinguisher ready -- if you like hot garlic, you'll love this one's slow start and building heat"
