I have cool weather veggies in the ground already, spinach, peas, lettuce and a perinnal artichoke plant that is really looking nice this year. I also have a bunch of sprouts going inside basil, thyme, catnip and some flowers hanging out on a window sill that I can put out in bout a month. I'll start tomatoes indoors soon too. The rest of the veggies must wait till at least May - beans, cukes, melon & sunflowers are what I have in mind atm.
I really want to do some long commitment fruits and veggies, like fruit trees, grapes and asparagus but I don't plan on staying in my house for more than a couple more years.
I love growing fruits and veggies more than flowers - It's a neat connection to mother earth to eat what you grow.
