The traditional Northwest method — sowing seed in late August for an early summer harvest — produces the most impressive results: very large, distinctly flattened bulbs with unparalleled sweetness and tenderness. Where winter temperatures stay above -10°F, overwintered crops achieve superior size and flavor. In colder climates, spring planting from seed or transplants still yields respectable bulbs, though somewhat smaller and less intensely sweet. Also lovely as a \"green top\" onion. Not a storage variety. Harvest in about 125 days.\u003c\/p\u003e\n\n\u003cp\u003e\u003cspan style=\"color: rgb(8, 74, 8);\"\u003e\u003cstrong\u003eGermination Rate: 80%. Test Date: 12\/25.
