Q: Can you tell me what a sansavarius plant is?

I think you might be talking about the genus Sansevieria, which is a houseplant with long, flat, wide leaves. The leaves are often mottled with shades of green. The species S. trifasciata is from Nigeria and Congo and is often called “mother-in-law’s tongue.”
