"Hard to believe it's been a year since losing Luke. Though time heals wounds, the pain of loss lasts forever. Miss you so much pal," Ziering captioned the picture.
While primarily a TV star, Perry did appear on the big screen and his final film role was in last year's acclaimed "Once Upon a Time ... in Hollywood," which won two Oscars.
Perry's death occurred a few months before the "Beverly Hills, 90210" reboot premiered last summer. While promoting the new series, Spelling and co-star Jennie Garth said working on the update helped them mourn his passing.
"The timing was something that seemed horrific, but in a weird sort of universal way," Garth told TODAY. "It was a way for us to all be together during (an) incomprehensible painful time. I think that was really good for all of us, actually. And he was with us every second of the time."
