[quote="TZ -OH6"]I found Sweet Spanish Yellow Utah Jumbo on the Ferry-Morse seed rack at Lowes (all of the other onion seeds were more or less wrong for my area--I've taken a lot of seed packs back after looking them up online). Walla Walla is another long day big sweet onion.
From what I understand you have to start onion seeds way early, or buy bunches of young onion plants. Last resort is to buy onion sets (little dried onions). Even my local hardware store is advertizing bags of 80 onion sets for $2, It's hard to find bundles of onion plants locally, but it may be possible if you have a good nursery around. Onion sets result in smaler onions that starting from plants, and some of them may bolt to flower/seed.
Thanks for all the info.
