Sansevieria “Futura Superba” is an evergreen perennial that grows on average to the height of 12 to 18 inches, reaching a maximum height of about 24 inches.
It is better to under water than to over water. Use only about maximum 1/4 cup of water every few weeks.
It doesn't require fertilizer, but will grow best if fertilized once or twice a year in spring or summer (or every six months) with a general-purpose houseplant fertilizer.
Sansevieria “Futura Superba” requires well-draining soil and soil that retains too much water will cause its roots to rot. It is one of the very few problems this Sansevieria can suffer from, so make sure it is planted in a soil mix with plenty of coarse material such as pine bark, coarse sand, and/or perlite.
