The Snake Plant which is also known as the Viper's bowstring hemp can grow as tall as 3 feet but most Snake Plants or Viper's bowstring hemp plants grow to 12 to 24 inches tall.
The Snake Plant is a great indoor plant because it can also help purify the air indoors so your indoor air quality will be much better.
I have several Snake Plants in my home and they do purify the air and I have a few that are 3 feet tall while most of my other snake plants are between 12 inches to 24 inches tall.
