I like to place the Snake Plant in an area with plenty of bright light. However, they can survive in any light level. Although Mother-in-law’s Tongue is tolerant of low light, it does best with bright, indirect light. Mild temperatures also help the plant flourish.
Variegated forms need more light and some say they can be more difficult to grow. However, I personally have not had any issues with any Snake Plant variety. There are even cute dwarf varieties like Sansevieria trifasciata ‘Zeylanica’. Commonly called Bird’s Nest Snake Plant or Dwarf Snake Plant. To learn about many different sansevieria varieties check out my post here. If you are specifically looking for Dwarf Snake Plants read my post here.
Keep in mind the pattern on snake plant leaves will tend to be brighter when exposed to more light. But, bright direct light may be too intense for the plant. Specifically, causing leaf sunburn or leaf drooping.
An ideal spot indoors is approximately 10 feet (3 meters) away from a West or South window. Although a North facing window is acceptable. However, long periods of Northern exposure may cause leaves to droop.
If you did place your Snake Plant in full sun without a gradual acclimation and it is showing signs of sunburn or drooping, move it to a shadier spot. Then, slowly transition it back to the sunnier area over a period of time.
Additionally, I like to turn the pot a quarter turn at each watering for even light exposure. This prevents it from stretching or leaning too much in one direction.
