in my area, MD, USA we plant garlic right after first frost as previously indicated, with some warm Indian summer weather, they may sprout, don't fret, if not, they will in spring, like fivetricks said, it'll be one of the first things up in spring. Garlic are pretty much pest free, some fertilizer in the spring will help em get going. the garlic will get about knee high, and bulbs will grow in the ground. I harvest mine in mid June when the tops start falling over. something they grow scapes, look like tiny garlic bulb on the stem, these are good to use in stir fry's and what not. so in mid june when I dig up the bulbs, i put them in my shed, shake the dirt off, and let them air dry for about 8 weeks. then I put them in a mesh bag and store them in a cool dry place. They will store for a good long time, I get almost a year of storage and go season to season. couple o other things, store bought garlic sometimes has inhibitor sprayed on the garlic in increase shelf life, mileage may vary. and do monitor the bulbs as as harvest date come close, if bulbs will begin to split apart, this will reduce storage life. after you've stored and dried the garlic, save your biggest and best bulbs for the next season. starter garlic can look expensive in the veggie magazines, but nor really when you can save some and plant again year after year, I've been running the same family for about 4-5 seasons now for that $5 or so bulb of garlic. last, around this time, most of the veggies magazine retailer are out of stock, If inclined, I would suggest to give the store bought garlic a try, and then in spring order something you like and plant next fall. there are many different types of garlic varieties, very different flavors, and I'll end by saying you'll have to do homework to research hard-neck and soft-next varieties, I've gone on long enough.
