I've been researching this a little more and have started the containers. I am going to plant per this list from a site:
Zone 6 Growing Guide
December: Perennial flowers and hardy annuals.
Broom Flower
Fleabane
Fountain Grass
Lily-of-the-Nile
Red Hot Poker
Sea Pink
Verbena
January: Most herbs and plants that require stratification.
Agrimony
Basil
Broccoli
Brussels Sprouts
Garlic (mine was already planted in October)
Hyssop
Kale
Madder
Onions
Peas
Sage
Spinach
Swiss Chard
February: Frost-tolerant vegetables.
Beans
Beets
Bok Choy
Lettuce
March: Tender plants.
Corn
Cucumbers
Eggplant
Melons
Peppers
Pumpkins
Sweet Potato Slips
Tomatoes
I don't grow all of these vegetables, but I just copied her list for you. Also, on her website she said something that I agree with: if you are just beginning and are not sure what to plant and when...experiment! Grow some seeds your traditional way with lights and heat mats and some seeds outside. I love the freedom of this advice!
