We planted all sorts of vegetables (after doing some research to see what would grow well in our climate and what would be least likely for me to kill - I'm not particularly green-thumb-ed) including carrots, lettuce, onions, snap peas, and herbs, as well as some flowers - zinnias and marigolds. I've heard it's pretty easy to grow marigolds. And did you know radishes only take 26 days to mature into ready-to-eat yummy-ness?!
I planted some roma tomatoes, but have read it is probably better (easier?) to just buy actual tomato plants (and green pepper plants) once the weather gets warmer.
So now we wait. Watch the cute little cans and jiffy tablets and wait. Once the seeds sprout and grow, we will transplant them to bigger containers and put them outside (when the warm weather is here to stay). For now, they will sit on top of the fridge where it is warm and have a "plant growing light" on them... which I still need to purchase ;).
