The seed catalogs have already begun to arrive. It is a little earlier than usual. Most of the catalogs I get I will not order from. Seed companies seem to like to sell your name, and send you catalogs from all of their daughter companies.
I made a mistake (back in the day) of ordering trees from a company the was in bed with Monsanto. I now know better and stick with companies that I have found to be more upfront bout their seeds. Jung's, is probably one of my favorites when looking at known seed companies. They clearly label their seeds as hybrids or heritage.
Skyfire Garden Seeds is a local company that I plan on trying out this year.
If you are looking for seeds (and yes, now is the time to start shopping) Here are some other good places,
Victory Heirloom Seeds
Baker Creek Heirloom Seeds
