I always recommend Baker’s Creek as well as Seed Savers and, of course, Jung’s.
I also have discovered Pinetree Garden Seeds. They sell smaller packets of seeds - less waste from year to year.
And Botanical Interests have the most LOVELY packaging and REALLY know how to Do It Right with your first order - beautiful seed packets, gorgeous shipping box, TONS of pamphlets and info sheets and free seed samples, too!

And Renee’s Garden is ALWAYS worth a look-see:
Ooooo, thank you!
