Yes, plant them out now. The seed wants the cold, and should come up next spring. If the soil is wet and muddy, you will want to wait until it dries some so it is workable. As long as it is above about 35°F, you can plant them. If you have them inside the house, then in the meantime, it would be best to gradually start the cooling process and keep them in the unheated garage, until you are ready to plant.
