Hardneck garlic is extra chilly hardy and greatest for northern climates. It requires the chilly winter (vernalization interval) to create full bulbs. Because the title implies, hardneck garlic has a stiff central stalk. They’re the one form of garlic that sends up buttery-delicious scapes (flower stalks) throughout the spring or summer season.
