what gives with these leeks!? I planted some (I got a free 'seed tape') back in July threw them into the garden after my broccoli was 'done'... and they just sort of sat there until a few weeks ago, and now they're HUGE! Are they like a cold weather veg? Did I COMPLETELY miscalculate as to when to plant them?? They taste great.. I just sauteed some. Yum. I most definately want to try them again next year... In in zone 5/6 in Northwest Connecticut... thx in advance!
