I just came across this website: https://www.horizonherbs.com/
Packed with information. I like the down-to-earth tone of the website too. Unfortunately (for me) they're based in Oregon and outside of "geologically/climatically compatible with my garden" area where I have decided to do most of my seeds and plants shopping. I do wonder if anyone else has had experience with Horizon Herbs?
My current favorite herb sources are my local herb lady: www.springvilleherbary.com and Mulberry Creek Herb Farm in Ohio: www.mulberrycreek.com/
