Papaver somniferum The biggest rattlepods we’ve seen! Bowling ball isn’t too much of an exaggeration when describing this poppy’s seed head, but tennis ball size is closer to the truth. Fleeting, pink-petaled blooms fade to developing the enormous pods on sturdy, 36–48 inch tall stems. For the largest pods, direct sow the seed in late summer to fall, and the overwintered crop will yield magnificent crops for a statement in dried arrangements. Approximately 2200 seeds per gram. Germination code: (4)
