The 22-year-old midfielder moves to Hillsborough for a month until Wednesday, March 12.
Gardner made 14 Premier League appearances for Villa in the 2011-12 season but has barely featured under Paul Lambert in the last two terms.
He will wear number 40 for the Owls and is eligible to make his debut in this weekend's FA Cup fifth-round tie against Charlton Athletic.
