you can plant it now but unless you have space to waste and don't mind TINY bulbs don't bother.
mine is already 6" tall - garlic should be planted in the fall. i'm in CT also and i plant the last week of oct or 1st week in nov. any variety will grow whether from the grocery store or from a farmer or from a seed company.
i advise you contact
http://wegrowgarlic.com and ask to be put on their mail list so you'll know when they have this year's harvest ready for sale to have the best choice of all their varieties.
i forgot to mention there's a fellow here called bloo who also sells garlic.
