I have ordered from Bakers Creek and Ohio Heirloom Seeds the last two years and have been very happy with both. Ohio Heirloom is working on a new website for next year I think. Collections – Ohio Heirloom Seeds
I also checked out sample seed shop after reading this thread and discovered the owner has unfortunately passed away.
I am looking for sources of some of the tomatoes discussed in this thread and some others so I’ll go through the other suggestions too.
Wintersown.org is broken
Wild Boar Farms is live
Tradewinds Fruit is live, they have Opalka tomatoes which I was looking for.
Chili Pepper Institute looks like a super cool option for those looking for some colorful spice
Skyfire appears to be a UK outfit with good ideas for different garden plants, not sure if they actually sell seeds. More of a blog.
Tomatofest is all organic and all tomatoes. They appear to have some interesting dwarf options. Chocolate lightning looks pretty cool.
Seeds from Italy is live
Diane’s Flower Seeds is live
Gourmet Seeds is live.
Pinetree Garden Seeds is live
Johnny’s Seeds is live
Park Seeds is live
Totally Tomatoes is live
@alan and @Drew51 thank you both for these sources. As someone who is just starting out, sometimes the “obvious” choices aren’t so easy to find. I added links for others who might not know where to start.
