HEIRLOOM These scrumptious Negi onions are bunching onions, most commonly grown in the US as scallions, though they’re a delicacy in Japan when hilled like leeks and grown 6+ months, allowing their flavors to deepen. Grill them, oh grill them! Just like scallions, Negi onions are perennial here in Zone 5 (hooray!) and ours have been thriving for years here at the farm. They’re such a sweet spring treat to harvest the first of them as the snows melt! If you allow even a few of them to overwinter, you’ll see their blooms the following summer, round orbs of sweet white flowers bustling with butterflies and bees.
