The 22-year-old spent the early part of the campaign on loan at Brighton & Hove Albion, where he made 20 appearances.
Gardner penned his first professional deal with Villa in 2011, but he has struggled for first-team action in recent times.
He could make his debut for Forest later today when they host Sheffield Wednesday in the Championship.
