The West Bromwich Albion midfielder has impressed his manager on and off the pitch of late.
The 29-year-old scored the opener in that game before setting up the second goal for Craig Dawson in a 3-2 win at The Hawthorns.
Earlier this month, Gardner added another goal to his tally, scoring the equaliser in his side's 2-2 draw at leaders Leicester City, and helped his side to all three points in their last outing against Manchester United.
Pulis' side have climbed three places in that time, and currently sit just a point away from a top-half place.
"He's as important off the pitch as he is on it," Pulis said, as quoted by the Birmingham Mail.
"He's such a great character to have around the place.
"He's old school - an old fashioned professional who's brilliant round the dressing room.
"He keeps everything bubbling and says what he thinks.
"I think he runs the players' pool, he does all of that.
"He's a top man Gards.
"I like people who are like that."
The Brummie midfielder has another 15 months to run on his Baggies contract.
He has appeared 67 times for his current employers in total, scoring on six occasions.
