This does not mean you're too late if you have no idea what I'm talking about. But don't order a catalog and wait for it to arrive - just check out their website. There are seeds you can try this spring that are still available. And there are other gardening goodies, too.growing French breakfast radishes from Peaceful Valley, and we'll be talking more about radishes later this week. If you have never grown a single thing before and if you only have one little pot on your windowsill - try one of Peaceful Valley Farm's varieties of radishes. Their seed collection is immense. They have their house brand of seeds, but also carry Seeds of Change, Horizon Medicinal Herb Seeds, Turtle Tree Biodynamic Seeds (one of my favorites), Renee's Garden Seeds, and TomatoFest (thirty one varieties!). Mushroom Growing Kits Metal Harvest Basket. Even if you don't have that much to harvest (say, you're gardening on a fire escape, stoop, or one pot on your deck), it's pretty hard to resist something that screams bounty in such an adorable way.
Now, this isn't the slickest of catalogs or websites, but it gets the job done. The prices are fair, and they even offer free seed packs depending on how much you spend.
