I also started with a snake plant that was my mothers'. That plant stayed with me for well over 40 years and bloomed often. Started with S. trifasciata Laurentii (yellow margins) which later gave me the all green ones S. trifasciata. Both pots grew over 4 ft. tall. I used tomato cages to help keep the leaves in order.
