Sansevieria francisii is a rather small Sansevieria species, which forms new runners every year, grown from the runner of my mother plant; potted in self-mixed permeable organic substrate; not over-fertilised (100% organic quality before quantity!, no GWHaus culture); slow growing; not winter-hardy, repotting only desired in 2-3 years; easy to care for, sunny to semi-shady location; no waterlogging.
All my Sansevierias from my collection (over 100 species) grow slowly, without being massively fertilised, with the growth pause in winter. As a result, they are top healthy, robust and simply look natural. Sansevierias are not hardy, as plants are supposed to clean the indoor air and increase the oxygen content in the house. Enjoy your new Sansevieria francisii!
