It's always best to get your seeds for a supplier as close as possible to where you live. If you can buy seeds that came from NH, you will have a better success rate than if you buy seeds from Georgia.
I have gotten seeds from a seller in zone 4B who claims their seed is from wild strains, to try to better match my climate. I just planted last year so I cannot attest to the results from their seeds. I know the people I ordered from seemed mom and pop, I spoke with real people, and they got seeds to me quickly, and on time for me to plant them during my vacation. I'm not sure about the etiquette here, so if you would like the the website I ordered from please send me a message, and I will certainly provide their info.
